    Fairway Park Shopping Center / Dry Cleaner 31049-31091 Mission Boulevard Hayward CA Cleanup Program Site Open - Eligible for Closure Tetrachloroethylene (PCE) Other Groundwater (uses other than drinking water), Soil, Soil Vapor The Regional Water Board began its oversight in September 2008. PCE concentrations in groundwater were found during environmental due diligence studies performed in 2006, 2007 and 2008. The PCE is believed to be from past dry cleaner releases of one or more former dry cleaners. Fairway Cleaners operated from 1959-1967 at #31061 located within the current building occupied by Fresh and Easy. Fairway Cleaners operated from 1967-1991 at #31078 located in the middle of the shopping center's northwest building at the rear entrance. Reportedly, two other dry cleaners State Dry Cleaners from 1967-1976 and Diamond Cleaners from 1980-1985, both operated at #31061 located in the northern portion of the main supermarket building currently occupied by Fresh and Easy at #31049 and the Dollar Tree retailer at #31047 Mission Boulevard. Between 2008 and 2015 AllWest Environmental consultants conducted phased investigations to determine the source pf PCE and the extent of the release(s). These investigations included collecting soil, groundwater, sub-slab vapor and in-door air samples within the space #31078 immediately adjacent to the dry cleaning equipment operated by Fairway Cleaners. To assess indoor air quality of adjacent businesses operating near the former Fairway Dry Cleaners, AllWest collected indoor air samples at Mountain Mikes, Taqueria Los Gallos, New Uppercuts, Ann's Beauty, and Fresh & Easy. The lateral and vertical extent of PCE was assessed with groundwater monitoring wells MW-9, MW-10 in the front parking lot and wells FMW-1, -2, and -3 in the rear parking lot. Groundwater flow direction has been calculated as west-northwest to north-northwest at a flat gradient (0.002 ft/ft). AllWest evaluated site data and cloncluded that the site is eligible for case closure since it meets the low-threat criteria in the guidance document Assessment Tool for Closure of Low-Threat Solvent Sites, Draft Final July 31, 2009. AllWest determined that the case meets the low-threat criteria. The Regional Water Board concurs that the PCE release has been appropriately investigated and there is no threat to human health and safety, based on the information currently available to staff. In September 2015, Staff approved a Low Threat Case Closure Report and required a Well Destruction Report.

Prior to 1944, the site was owned by the State of California. Chrysler purchased the site in 1944 and conducted vehicle parts manufacturing operations on the site from 1952 to 1962. Vehicle parts manufacturing and assembly operations were continued by subsequent owners International Harvester (1962-1976) and Caterpillar (1976 to 1986). In 1987, the site was acquired by Monarch Ventures, the current property owner, renovated the structures and converted them from industrial uses to the current property uses. President Tuxedo conducted dry cleaning activities using Tetrachloroethylene (PCE) in three tenant spaces from 1989 to 1999.

The samples indicated that both soil and groundwater were impacted by volatile organics at concentrations of up to 3.1ppm PCE in soil and 230 ppb PCE, 14 ppb TCE 25 ppb cis-1,2-DCE and 7.6 ppb vinyl chloride. A Subsurface investigation was performed on May 24, 2005 to evaluate the extent of the dry cleaners solvent in soil and groundwater. This investigation determined that PCE concentrations were detected in off-site groundwater * SA Clorox Technical Center Pleasanton - Former Clorox Campus - Building 7 7164 Johnson Drive Pleasanton CA Cleanup Program Site Open - Site Assessment Tetrachloroethylene (PCE) Indoor Air, Soil, Soil Vapor 7/7/2015: This Site was part of the Former Clorox Campus Site (SCP No.01S0749).

HOPYARD CLEANERS 2771 HOPYARD RD PLEASANTON CA Cleanup Program Site Completed - Case Closed Tetrachloroethylene (PCE) Other Groundwater (uses other than drinking water), Soil, Soil Vapor The Responsible Party has been proactively moving forward on all phased of investigation and remediation. Based on the available information, there are no potential human exposure routes to the chlorinated VOC contamination. The groundwater-CVOC plume appears to be stable and not expanding and soil-CVOC plume is confined on-site and under the dry cleaners facility. Since October 2008, soil vapor extraction has been successfully removing CVOCs in soil gas under the dry cleaning facility. The final groundwater remedial action will either be in-situ chemical oxidation (ISCO) or enhanced in-situ bioremediation (EISB).

A more complete historic case file for this site is located on the Alameda County Environmental Health website at https://ehgis.acgov.org/dehpublic/dehpublic.jsp. A dry cleaner operated in the middle suite of a three unit single-story building. The dry cleanear operated from at least 1968 through 1999. A Phase II investigation, consisting of advancing 4 borings, revealed the presence of tetrachloroethene (PCE), at each of the boring locations. PCE soil concentrations were reported at up to 5.5 mg/kg. One soil sample was reported to contain 1,2,4-trimethylbenzene at a concentration of 0.023 mg/kg. PCE concentrations were reported in all of the grab-groundwater samples in the borings at concentrations of up to 16 micrograms per liter (╡g/L ). The compound tertiary butyl alcohol (TBA) was also reported in the four groundwater samples at concentrations of up to 10 ╡g/L.

Further investigations occurred in 2012 and 2013. This Site qualifies as a Low-Threat Chlroinated Solvent Sites pursuant to Assessment Tool For Closure of Low-Threat Chlorinated Solvent Sites, Draft Final - July 31, 2009 (Regional Water Quality Control Board, San Francisco Bay, Groundwater Committee), as follows:. 1. Pollutant sources are identified and evaluated. 2. The site is adequately characterized. 3. Exposure pathways, receptors, and potential risks, threats, and other environmental concerns are identified and assessed. 4. The site presents no unacceptable threat to groundwater and surface water resources, considering existing and potential beneficial uses of water. 5. Groundwater objectives are met for all constituents. 6. Remediation was not warranted. Site Management Requirements: The site in an operating dry cleaner. As with any dry cleaners, there is always a possibility of unauthorized releases of chemicals stored and handled at the site. We therefore recommend the following: 1. Business operations must comply with all applicable State and Local regulatory agency (i.e., California Unified Program Agency) requirements. 2). Prior to any proposed use of shallow groundwater in the immediate vicinity of the site, groundwater samples should be collected to confirm groundwater is not impacted by VOCs. 3. Additional soil sampling in the vicinity of the former dry cleaners operations should be conducted if land use changes to residential use. 4. Remediation should be conducted, if warranted, based on the results of soil and groundwater sampling, if any.

Site Assessment/Site Investigation Phase II Environmental Site Assessment Dry Cleaners Operation Ceased CROW CANYON CLEANERS 7272 SAN RAMON DUBLIN CA Cleanup Program Site Open - Site Assessment ALAMEDA COUNTY LOP Tetrachloroethylene (PCE) Aquifer used for drinking water supply The site is located in a suite within a commercial building located on the west side of San Ramon Road, within a mixed residential/commercial area of Dublin, CA. One of the units of the building (7272 San Ramon Road) has been occupied by a dry-cleaning facility since 1988. The dry-cleaning and solvent storage areas were located in the back of the building, with PCE used as the cleaning solvent until 2004. AEI performed a preliminary subsurface investigation at the property in 2005. Three shallow soil samples and three groundwater samples were analyzed for halogenated volatile organic compounds (HVOCs). PCE was detected in all the soil and groundwater samples analyzed. Between December 2006 and January 2007, AEI performed another subsurface investigation by advancing five soil borings throughout the property; two borings (SB-14 and SB-15) were advanced near the front of the dry cleaning facility, down-gradient from the dry-cleaning facility. Two borings (SB-11 and SB-12) were advanced at the rear of the dry-cleaning facility. One boring (SB-13) was advanced adjacent to the sewer line trace inside the Montessori School. trichloroethylene (TCE) were detected in groundwater at relatively low concentrations (PCE was detected at 0.78 to 2.5 ug/L in the shallow water-bearing zone, while TCE was detected in one sample at 1.1 ug/L; no other HVOCs were detected in either zone). In addition, PCE was detected in all four of the soil vapor samples analyzed, at concentrations ranging from 270 μg/m3 to 380,000 μg/m3 (SB-11-V-D). TCE was detected in three of the soil vapor samples at concentrations ranging from 4.4 μg/m3 to 3,200 μg/m3 (SB-11-V-D). The boring (SB-13-V-D) located along the sewer line trace within the footprint of the Montessori preschool contained PCE at a concentration of 6,800 μg/m3. Other investigations have verified elevated PCE in soil vapor. A Corrective Action Plan has been submitted and is currently in public notification/public participation phase. * SA Tower Cleaners 1110 University Avenue Berkeley CA Cleanup Program Site Open - Site Assessment BERKELEY, CITY OF Tetrachloroethylene (PCE) Other Groundwater (uses other than drinking water), Soil, Soil Vapor Dry cleaning solvent, perchloroethylene (PCE) recognized in shallow soil and groundwater samples.

Both dry cleaner operations resulted in a release of tetrachloroethene (PCE), a formerly-used dry cleaning solvent, into the soil and groundwater. The groundwater plumes from each site have mingling with each other and migrated toward the northwest, extending under the residential area and have reached a municipal water supply well. This water supply well has been equiped with a treatment system to remove the PCE from drinking water supply. The concentrations and depth of PCE migrating in groundwater under the residential area downgradient of the sites do not pose a vapor intrusion threat to indoor air. However, solvent vapors at the release points under the existing and former dry cleaners may pose a threat to overlying indoor air, and are undergoing soil vapor extraction testing. Groundwater cleanup through injection of a vegetable oil-based substance to stimulate the natural breakdown of the contaminants was tested at the site and is proposed for groundwater downgradient of the site.

The site was occupied by a Canada Dry bottling plant from the time of its construction to 1978. The southern half of the site building was occupied by Perc-Serv, Inc., a wholesale laundry and dry cleaning supply business, from 1978 to 1983. In 1985, the project site building was renovated as multi-tenant retail, office, and warehouse uses, which is its current use. A 1955 permit for installation of one 7,500 gal UST w/TPHg and a 1978 permit for removal of the UST have been identified. Soil and groundwater samples from the loading dock area on the west side of the Site showed elevated levels of some halogenated volatile organic compounds (HVOCs), indicating, primarily, tetrachloroethylene (PCE), trichloroethylene (TCE) and cis-1,2-dichloroethylene (c-1,2-DCE). Groundwater impacts are primarily recognized to approximately one block west-southwest from the Site to Eighth Street and do not appear to extend to the south which is predominantly a residential neighborhood. Gasoline constituents associated with the former UST include benzene, a recognized carcinogen.

Investigations have found Tetrachloroethane (PCE) in soil and groundwater underlying the Site and the PCE plume has migrated off-site approximately 200 feet in a southlerly direction. A cleanup plan dated June 30, 2015, has been approved by the Regional Water Quality Control Board and a public notification fact sheet was distributed to interested parties. The cleanup includes the following: - Building demolition of a 6,000 sq-ft structure - Soil excavation. 500 to 2,000 cubic yards of soil will be removed to a depth of 14 feet below grade where groundwater is anticipated to be encountered - Enhanced biodegradtion using emulsived veretable oil for groundwater remediation - Groundwater monitoring - Reporting The 30-day building demolition notification period ended May 15, 2015 and demolition was completed in early June 2016. Soil excavation for remediation of VOC impacted soil is anticipated to be completed during late June and July 2016. Groundwater Monitoring Due dilligence environmental investigations Cease operations Berth 57 - Port of Oakland 1717-A Middle Harbor Road Oakland CA Cleanup Program Site Open - Remediation Tetrachloroethylene (PCE) Other Groundwater (uses other than drinking water) PCE at levels exceeding DNAPL threshold was inadvertantly discovered by the installation of well UO1-8. The PCE contamination appears to be hydrogeologically controlled by the nearby 30-foot thick cement deep soil mixing wall described below. The Port indicates that the source of the PCE is not from the former dry cleaning facility located in the former FISCO area. Remedial investigations defined the lateral and vertical extent of the PCE in the UO1-8 area. The 7Feb10 CAP evaluated excavation, chemical oxidation, thermal treatment, groundwater extraction, and natural attenuation and selceted chemical oxidation. The Port's bench-scale lab study (Study) did not determine how high the soil oxidant demand is in the UO1-8 area and is in the process of re-evaluating their Study. In year 2000, the Port installed as part of their Vision 2000 program: - Engineered concrete cap with an effective thickness of 6 feet over and beyond the TOFC area - Cement deep soil mixing (CDSM) wall with a width of 30 feet along the edge of the Oakland Inner Harbor as a geotechnical stabilization structure. - Slurry wall north of the CDSM wall The concrete cap effectively isolates the diesel and other subsurface contaminants from potential human exposure. The CDSM wall has a very low permeability that effectively isolates the PCE area around well UO1-8 from the Oakland Inner Harbor. Along with the slurry wall, the CDSM also effectively isolates the diesel area from the Oakland Inner Harbor. Given the thorough isolation, diesel plume shrinkage and stability, and low hydraulic gradient, the Water Board is on the verge of granting TOFC site closure pending the resolution of deed restriction and SMP questions. The Water Board is presently reviewing the UO1-8 remedial action plan.

Historical records indicated that the subject property operated as a dry cleaning facility since the building construction in 1965. Prior to that, the property was undeveloped land. In September 2010, the dry cleaning equipment was decommissioned and removed from the site. In October and November 2010, approximately 75 tons (50 cubic yards) of PCE-impacted soil was excavated and transported offsite for disposal. Low levels of PCE were detected in each of the confirmation soil samples but only one collected at the northeast corner of the excavated area exceeded the Regional Water Board?s Environmental Screening Level (ESL) for commercial/industrial land use. Low levels of PCE were also detected in confirmation groundwater samples but none exceeded the ESLs for drinking water or vapor intrusion. On November 2, 2011, a land use covenant and environmental restriction was recorded with the County of Alameda which restricts use of the subject property to industrial, commercial, or office space and prohibits the drilling of water supply wells on the property.

Formerly the site was used by Unique Cleaners. Currently the site is used by OK Cleaners & Laundry. Two rounds of sampling were conducted at the site in 1988 and in November 1990. Up to 1.3 ppm of PCE, 0.19 ppm of TCE, 0.570 ppm of 1,1,2,2-tetrachloroethene, 0.470 ppm of methylene chloride, 0.015 ppm of chlorbenzene were detected in soil samples collected at the site (at 0.5 to 10 feet bgs), and within capilary fringe off-site. Up to 4,400 ppb of PCE, 12 ppb of TCE, and 2.98 ppb of dichloroethene were detected in off-site well P-3 located immediately downgradient (south ) of the subject site. The dissolved VOC plume was delineated to nondetectable VOCs concentrations in downgradient wells/borings P-8 and PHP-2, or low VOC concentrations (3.8 ppb of PCE and 1.4 ppb of TCE) in downgradient wells PMW-1 and P-9. No additional environmental work was performed at the site after the November 1990 sampling. In 1990 the site was overseen as a part (area of concern #4)of UST case 07-0123. UST case 07-0123 was granted a closure in respect to petroleum contamination (only) on April 25, 2003. Therefore, the VOC case was opened as a separated SLIC case 07S0161.Based on the site inspection it appears that wells P-9 and PMW-1 no longer exist (were destroyed or paved over). Well P-3 has not been used since 1990, and well condition is unknown. This well will be destroyed with allother wells related to UST case 07-0123. Currently the site is used by OK Cleaners & Laundry. The site is bounded by a residential property to the east, commercial properties to the west (Best Inn hotel) and north, and Potrero Avenue (and commercial properties across the street) to the south. Confirmation sampling shall be conducted at the site to confirm current VOC concentrations in soil and groundwater. * Other Means Custom Cleaners 2575 main street oakley CA Cleanup Program Site Completed - Case Closed Tetrachloroethylene (PCE) Soil Vapor A dry cleaner operated between about 1990 and 2009.

The Site was historically used, from 1965 to 1986, to store bulk tetracholoroethene (PCE) in an aboveground storage tank at the northern section of the property. Soil and soil vapor surveys in 1996 indicated the presence of PCE. Several monitoring wells were installed in 1996 and showed PCE in the underlying groundwater. In 1998 a vapor extraction system was installed and ran until 2004. The extracted soil vapor is treated using two 2500-pound activated carbon vessels to remove the VOCs. Through subsequent testing a series of groundwater monitoring wells have been installed and continue to be monitored quarterly. Four new offsite SVE wells were installed during late 2008. An SVE system is currenlty extracting soil vapors from five vapor extraction wells located near the highest concentrations of PCE in groundwater and soil. This is located just downgradient of the site. Investigation to assess the lateral and vertical extent of impacts to groundwater is ongoing.

According to the information provided in the Phase I the Site was first developed in 1928. A tenant space within Building B was occupied by a dry cleaner. In addition, auto repair operations formerly conducted in Building F since the 1930s until 1997. The dry cleaning and auto repair formerly conducted at the Site were identified as potential contaminant sources that require further investigation. Accordingly a limited soil and groundwater sampling and analysis program was carried out at the Site. The analytical data confirmed that soil and groundwater beneath the Site are impacted with Volatile Organic Compounds (VOCs) including tetrachloroethylene (PCE), trichloroethylene (TCE), dichloroethylene (DCE) and others. The findings are consistent with the documented use of PCE at the former dry cleaner. The Site is located in the West Coast Basin of the Los Angeles Coastal Plain. The subsurface investigation included six exploratory borings. The report describes that the soil types as primarily of silty clay with occasional sand.

Petroleum hydrocarbons (primarily diesel- and oil-range) were also detected in shallow soil as a result of former auto repair. The highest concentrations - 1,970 milligrams per kilograms (mg/kg) total petroleum hydrocarbons as diesel (TPHd) and 5,750 mg/kg total petroleum hydrocarbons as motor oil (TPHmo) ? were detected at 1 foot below ground surface (bgs). Maximum PCE concentrations in soil were 5,700 micrograms per kilogram (╡g/kg) at 5 feet bgs and 7,700 ╡g/kg at 10 feet bgs. The highest concentration detected in soil vapor was 237 micrograms per liter (╡g/L) at 5 feet bgs, which exceeds the California Human Health Screening Levels (CHHSLs) for PCE of 0.603 ╡g/L for commercial/industrial use and 0.180 ╡g/L for residential use. The maximum concentrations in soil and soil gas were found to be associated primarily with two former dry cleaner facilities located at the northern end of the Site. Groundwater grab samples were collected from six locations, including one of the primary source areas. The groundwater was encountered at a depth of 85 feet bgs. PCE was detected in only two groundwater samples at concentrations of 8.8 to 44 ╡g/L. Some additional groundwater investigation is needed but preliminary data suggest that groundwater impacts beneath the Site may be relatively minor. Based on the soil data and instrument field-screening during the investigations, the vertical extent of contamination in soil appears to be 25-30 feet bgs. Based on these data, soil excavation is tentatively being considered as the best remedial option for the redevelopment. The limited soil gas investigation by Geosyntec in early February 2012 suggests that the soil vapor plume impacts occur primarily onsite and generally do not appear to be a significant threat to the offsite neighboring residential properties to the west. However, as discussed in the February 28, 2012 meeting, soil vapor plume delineation and monitoring, and a site specific human health risk assessment (HHRA) have not been completed. In March 2004, Capital Vision Equities (Capital) requested assistance from the Regional Board to provide oversight for a planned residential redevelopment of the Site. Following Capital?s acquisition of the property, the developer filed bankruptcy and defaulted on $962 million in loans and assets. The Site was in cost recovery, but none of the Regional Board?s oversight invoices were ever paid by the property owner. For the next six years, the property was tied up in bankruptcy and could not move forward. In late 2010, a settlement agreement was reached and one owner, Commercial Property Managers, was in control of 80 percent of the property, whereas 20 percent remained with the Community Redevelopment Agency of Los Angeles (CRA/LA). On February 20, 2012, Regional Board staff and management learned that Kaiser Permanente (Kaiser) is interested in constructing a commercial medical office building (not a hospital) at the Site. On February 22, 2012, Regional Board staff held a conference call with representatives from Marlton Associated Recovery Partners (MARP), the current owner, and Kaiser to discuss the Regional Board?s oversight process, remediation and closure requirements, and timeframes. Subsequently, on February 28, 2012, Regional Board staff and management met with Geosyntec, Kaiser?s consultant, to discuss the results of recent soil, soil vapor and groundwater investigations in December 2011 and February 2012, as well as proposed remediation options and soil vapor concerns. The purpose of the meeting was to provide Kaiser an understanding of the Regional Boards concerns and requirements regarding this Site prior to Kaiser?s acquisition of the property. Kaiser acquired the property in March 2012 and all of the former structures at the site have been demolished. On April 1, 2013, Kaiser signed a cost recovery agreement with the Regional Board to provide cost reimbursement for environmental oversight under the Regional Board's Site Cleanup Program for investigation and remediation that will be needed for the planned redevelopment. Geosyntec has submitted a workplan for site investigation dated April 10, 2013 that is currently under review by Regional Board staff. On June 19, 2013, the Regional Board issued an approval letter for Kaiser's April 10, 2013 "Additional Site Subsurface Investigation Work Plan". The workplan included a April 10 2012 "Site Subsurface Investigation Report" that documented results of a limited soil, soil vapor and groundwater investigation for Kaiser prior to their acquisition of the property. The April 10, 2013 workplan was meant to be an expansion of that initial work. The workplan proposed 12 direct-push soil borings to further delineate the lateral and vertical extent (to 30-foot depth) of PCE-impacted soil onsite. Six shallow (5-foot) soil vapor monitoring points were installed offsite in adjacent residential areas. The soil vapor probes will be monitored quarterly until at least six months following soil excavation. Three groundwater monitoring wells will be installed to further investigate deep soil conditions and further characterize groundwater quality beneath the site. The investigation work was conducted in June and July 2013. Regional Board staff reviewed the September 20 2013 "Additional Site Investigation Report" and found the PCE-impacted soils onsite to be sufficiently characterized to move into the soil cleanup phase. In addition, the groundwater monitoring results and data from deep soils beneath known source areas showed that the groundwater beneath the site was not impacted with site-related contaminants of concern. In a November 4, 2013 Regional Board letter, Kaiser was required to submit a Removal Action Workplan (RAW) to address the cleanup of relatively shallow PCE-impacted soils onsite. On January 15, 2014, Kaiser submitted their RAW to address the cleanup of PCE-impacted soil and soil vapor beneath the site. The RAW evaluated two common remedies for VOCs removal in soil: 1) remedial excavation/disposal of soil; and 2) soil vapor extraction (SVE) remediation. Kaiser selected remedial excavation/disposal based on cost, implementation, schedule constraints for redevelopment and probability of success. Regional Board staff reviewed and approved the RAW in a March 24, 2014 letter and subsequently reviewed and approved a companion March 27, 2014 "Removal Design and Implementation Plan (RDIP)" in a May 28, 2014 letter. Kaiser plans to conduct the remedial soil excavation work starting in mid-September 2014. The work should take about 2-1/2 months to complete. The Site is currently an 8.65-acre fenced, vacant commercial property in a mixed commercial/industrial and residential area of Los Angeles and occupies a portion of the Former Marlton Square Shopping Center. Five properties were listed with environmental concerns: four dry cleaners and one auto center. These activities occurred from the mid-1950s until the middle to late 1990s, at which time these businesses ceased operations and were subsequently abandoned. In July 2012, the vacant buildings and asphalt-paved parking lot was demolished. As a result of former dry cleaning operations, soil and soil vapor were impacted with chlorinated VOCs, primarily tetrachloroethene (PCE). Results of previous site investigations indicated that the PCE in soil was primarily distributed in shallow soil in two areas onsite, a western and eastern area, each associated with former dry cleaners onsite. The maximum PCE concentration detected in shallow soil (5 feet depth) was 17,000 micrograms per kilogram (╡g/kg). In May 2015, Kaiser conducted remedial soil excavation and offsite soil disposal to remove PCE-impacted soil from the Site. The soil remediation was conducted as part of Kaiser?s plans to redevelop the property with a commercial MOB. The soil remediation was implemented based on a January 15, 2014 Removal Action Workplan (RAW) and a March 27, 2014 Removal Design and Implementation Plan (RDIP), which were approved by the Regional Board on March 24, 2014 and May 28, 2014, respectively.

In October 1987, Teledyne ceased operation at the Site and sold the Teledyne Linair Engineering division to the Aeroquip Corporation, a division of Aeroquip-Vickers, Inc. (which has been merged into Eaton Aeroquip, LLC (Aeroquip)), who operated on a portion of the Site through a lease from Teledyne, who remained the property owner. In October 1990, Aeroquip terminated operation and vacated the Site. Between October 1990 and May 1996, the Site was mostly vacant. In May 1996, Teledyne sold the Site property to Radiant, which then began a commercial dry-cleaning operation at the Site. Radiant is a Responsible Party (RP) because it has discharged wastes at the Site, and being current operator and property owner at the Site. TDY is an RP due to the past operation, discharge of wastes, and property ownership by Teledyne at the Site. Periodically between 1967 and 1990 electroplating and degreasing activities were conducted at the Site, and between1996 and present commercial dry cleaning operations have been conducted at the Site.

MARIA STREET RANCHO DOMINGUEZ CA Cleanup Program Site Completed - Case Closed Tetrachloroethylene (PCE) Aquifer used for drinking water supply The subject property is approximately 2 acres in size, located at 2937 Maria Street, Rancho Dominguez, California. The current property owner is Maria-Reyes Properties. Prior to 1969, the subject site was part of a large agricultural tract in the area. The site was developed in 1969 with the present structure for use by Patrick Carpet Mills. Tetrachloroethene (PCE) and 1,1,1-trichloroethane (1,1,1-TCA) are chemicals known to have been historically used at the site. Based on drilling records collected by Targhee in 2007, soil types in the first 70 feet below ground surface (bgs), consists mainly of fine grained to very fine grained sand and silty sand, with interbedded silt and clay layers. First groundwater at the site was encountered at approximately 39 to 40 feet bgs during June 2007 sampling event. The groundwater at the site was flowing in a southwesterly direction at a gradient of 0.091%, or about 4.8 feet per mile (September 2007, Targhee). Subsurface investigations conducted in 1995 and 2003 identified an area of PCE-impacted soil in the vicinity of northeast corner of the building. From May 2005 to February 2006, Maria-Reyes Properties conducted soil remediation using a soil vapor extraction system (SVES), under the oversight of County of Los Angeles Fire Department, Health Hazardous Materials Division. Subsurface investigations conducted at the site prior to operation of the SVES identified PCE in soil at concentrations of 413 micrograms per kilogram ("∞g/kg") in sample VW1-5' and 276 ∞g/kg in sample VW4-25?. The highest soil-vapor concentrations were detected at 888 micrograms per liter ("∞g/L") at SVE5-34 and 1,100 ∞g/L at SVE7-44. The SVES was initiated in May 2005 and operated for six months at which time the inlet concentrations measured had become asymptotic. The SVES was turned off in December 2005 to allow the soil vapor to equilibrate in preparation for rebound testing. Ten of the fourteen existing soil vapor probes were sampled on February 21, 2006. (Probes SVE1-10 and -20 and SVE3-10 and -20 were not tested due to the low concentrations encountered in the initial testing and their proximity to probes SVE2/7.) Eight of the ten vapor probes sampled contained no detectable concentrations of VOCs. Samples SVE2-20 and SVE5-34 contained PCE at 1.6 and 11 ∞g/L, respectively. The PCE soil-vapor concentrations for samples SVE5-34 and SVE7-44 have been reduced from 888 to 11 ∞g/L and 1,100 to <1.0 ∞g/L, respectively. The reductions in soil-vapor concentrations achieved by operation of the SVES exceed 98%. Based on the results of the February 2006 soil-vapor sampling and the soil sample analysis from boring MW4 (at or near the source area), the SVES has adequately removed the PCE from soil at the northeast corner of the building. In June 2006, County of Los Angeles Fire Department determined ?no further action? for soil at the site (copy attached). However, County of Los Angeles Fire Department referred the case to Regional Board in June 2006, because the underlying groundwater contains volatile organic compounds. Based on the up to 12 rounds of groundwater monitoring and additional delineation via the recent hydropunch groundwater sampling, the residual VOCs in the underlying groundwater are stable and will not pose threat to human health and groundwater resources. The available data indicate the presence of an upgradient off-site source of 1,1-Dichloroethane (DCA) and 1,1-Dichloroethene (DCE), which is not contributed from the subject site. On June 30, 2008, Regional Board have determined that no further action (NFA) is required for the referenced property. The NFA decision was made based on the most current information in the subject file, and with the provision that the information provided to Regional Board staff was accurate and representative of site conditions. If new contaminated soils are encountered during future site construction activities, you are required toprovide verbal notification to this Regional Board immediately and submit a follow-up written report within 72 hours. In addition, appropriate health and safety measures must be fully implemented. Any contaminated soils that may be removed from the site shall be removed only to a legal point of disposal.

VIRCO PROPERTY 15134 SOUTH VERMONT AVENUE GARDENA CA Cleanup Program Site Completed - Case Closed Tetrachloroethylene (PCE) Other Groundwater (uses other than drinking water) The Former Virco facility operated at the site from 1952 to 1994 in the manufacturing of school furniture, with processes that included making tubular metal from flat steel, welding painting, enamel painting finishing, metal finishing, woodworking, and laminating. Several features at this facility included: metal plating area, sumps, wastewater treatment area, paint line, maintenance and machine shop, hazardous materials storage area, stormwater collection area; which were removed in the late 1980s and early 1990s. The facility used and stored plating solutions, acids, bases solvents, paints and thinners. From 1988 to 2006, numerous investigations and soil remediation were conducted at confirmed and suspected contamination source areas. Metal impacted and petroleum hydrocarbon impacted soil was excavated and transported to an offiste facilty for disposal. In the early 2000s, soil confirmation samples were collected throughout the site. This sampling did not reveal evidence of any significant residual soil contamination source at the site. Groundwater monitoring wells were installed in 2006, and samples were collected for six consecutive quarters. Volatile organic compound concentrations in groundwater are below or similar to their California drinking water maximum contaminant levels. On September 13, 2011, the Los Angeles Regional Water Quality Control Board issued issued a No Further Action Determination for the site. SATICOY CLEANERS (FORMER) 20175 SATICOY ST.

The Site is located within the physiographic feature known as the El-Segundo Sand Hills. Hydro-geologically, the Site is located in the West Coast Basin of the Los Angeles Coastal Plain. The material underlying the Site consists of fine to medium grained sand with some silt and gravel lenses. Three distinct aquifers lie beneath the Site. The top most Old Dune Sand (ODS) aquifer is followed by the Gage and Silverado aquifers. Depth to the first groundwater table is about 78 feet below ground surface (bgs), and the groundwater flow direction is to the east. Previous investigative work was performed during due diligence assessments prior to completion of site redevelopment, before Water Board oversight commenced. These environmental investigations included soil sampling and analysis for constituents including total recoverable petroleum hydrocarbons (TRPH), chlorinated and aromatic volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), polychlorinated biphenyls (PCBs), chlorinated herbicides, chlorinated pesticides, and California Code of Regulations (CCR) Title 22 metals. In June 2000, during grading for Site redevelopment of an area of apparent limited near-surface soil VOC impact onsite, which was evident based on odor and visual staining. Results indicated maximum concentrations of 54.2 milligrams per kilogram (mg/kg) of tetrachloroethene (PCE) and 0.034 mg/kg of methylene chloride. According the Report, Kleinfelder did not identify the types of activities historically performed at the Site including the two former companies (Bates Engineering and R&M Associates) that were occupied in this area. Subsequent to that discovery, extensive investigative and remedial activities took place. Based on the results of investigation and interim remedial actions, Kleinfelder requested NFA for the Site in 2005. The Case wa tranfered to DTSC in early 2007 and return to the Regional Board in late 2007. Since 2012, several additional site environmental work including soil gas and human health risk assessment assessments were conducted. Based on the results most recent work in this project, Regional Boar staff concluded that the Site is qualified for no further action (NFA) for soil and groundwater. However, a Pre-NFA notification was send out on February 9, 2016 for several interested parties in this project (2/9/2016 for former Fairchild and 11/4/2016 for TRW. No comments were received by this Regional Board regarding the no further action letter from TRWC. However, on March 9, 2016, Bowyers Environmental Consulting (BEC) on behalf of Fairchild submitted a report entitled ?Off-Site Investigation Report? (Offsite Report) to the Regional Board. The Offsite Report presented the results of 2015 soil and groundwater assessment conducted by Fairchild at the downgradient of the Fairchild including former AutoNation facility.

The Site currently consists of several single-story buildings, canopies, and paved parking areas used for auto body repair and paint work. The Site is located in an area designated for mixed residential and commercial use by the City of Los Angeles. ). The Site is located in the northern part of Central Basin of Los Angeles County. Soils types observed during previous subsurface investigations at the Site have been described as alternating intervals of predominantly unconsolidated fine grained sands, silts, silty sands, and some clay down to approximately 30 feet below ground surface (bgs). Based on the sampling results from the deep borings, AEI consultants (AEI) indicated that several sandy intervals were observed at approximately 26, 40, and 54 feet bgs. Depth to first groundwater at the Site has consistently been recorded approximately between 14 and 19 feet bgs in monitoring wells MW-1 through MW-4 since their installation in 2003. Since 2003, AEI and Terracon has conducted several rounds of phase II environmental investigations at the Site. Analytical results of the soil, soil gas and several round of groundwater samples confirm that the soil , soil gas and groundwater beneath the Site have been impacted with total petroleum hydrocarbon (TPH), and volatile organic compounds (VOCs) consisting primarily of tetrachloroethylene (PCE). Based on the results of most recent site investigtion conducted by Terracon in June 2009, on February 18, 2010 the LA RWQCB issued a directive letter to Fleiner Family Trust to initiate preparation of a Remedial Action Plan (RAP) to address the current impacts to soil, soil vapor, and groundwater at the site. The RAP should include an engineering assessment of all the existing data to evaluate the most appropriate, efficient, and feasible remedial alternatives to mitigate the subsurface impacts. In March 2010 Terracon prepared the RAP and proposed the following remedial technology for VOCS impacted soil, soil vapor and groundwater beneath the Site: 1-In-situ SVE remedial system was proposed for remediation of soils/soil vapor at the Site 2--Enhanced in-situ Bioremediation (EISB) in a Permeable Reactive Zone (PRZ) arrangement for impacted groundwater in down-gradient monitoring wells which has the highest concentrations of VOCs in groundwater. Based on new data in Data Gap Report dated February 2016, the Regional Board staff concluded the following: ? Results of 4 GW monitoring events in new installed MW-12 located offsite to north of the property boundary indicated that an anomalous GW elevations data. This anomalous data was not adequately interpreted by NOREAS. Consequently, groundwater flow direction was not correctly illustrated at the vicinity of the MW-12. ? New soil vapors and GW investigation results located at offsite to north of the property indicated that, offsite soil vapor and groundwater plumes were not significantly contributed to the onsite VOC in soil vapor or GW plumes ? VOC (PCE) vapor results at 5 and 10 feet indicated the concentrations of PCE still exceeded of acceptable levels for the offsite residents ? Extend of these PCE concentration to the west and south are unknown ? A limited and short time SVE system operation (8 months) was not effectively remediated of the soil vapor beneath the site. ? Active groundwater remediation is required to reduce the contaminants to meet the cleanup goals for offsite resident (according to HHRA). Due to long term process for MNA and uncertain effectiveness of this passive technology, the proposed MNA cannot be accepted Therefore: FFT is required for the following: 1. Step out soil vapor and groundwater sampling to the west and south west to delineate extent of Soil vapor and groundwater exceeded RBC for the current and future residential land use. Implementation, operation and monitoring program for of full-scal SVE system for soil and EISB pilot testing for groundwater are currently in progress. 88 DRY CLEANERS 1131 EAST LAS TUNAS DRIVE SAN GABRIEL CA Cleanup Program Site Completed - Case Closed Tetrachloroethylene (PCE) THE VIRGINIA JUSTINE BROWN INTER VIVOS TRUST 13702 VENTURA BLVD SHERMAN OAKS CA Cleanup Program Site Completed - Case Closed Tetrachloroethylene (PCE) Aquifer used for drinking water supply PALOS VERDE CLEANERS 2221 PALO VERDE AVE LONG BEACH CA Cleanup Program Site Open - Verification Monitoring Tetrachloroethylene (PCE) Other Groundwater (uses other than drinking water), Soil, Soil Vapor The subject site is located within the Palo Verde Plaza at the northwest corner of Stearns and Palo Verde Avenues.

The 1926-square foot Site is located within the Sherman Way Station strip mall. The strip mall has a parking lot north of the building that accesses Sherman Way. A separate paved parking lot is present to the south of the strip mall and separated from it by a 20-foot-wide alley. The Site was occupied by Smart Cleaners from 1987 to 2002. Swiss Cleaners has occupied the Site since 2002. The dry-cleaning machine currently in use at the Site is reportedly a Lindus Model ML45.2001 closed-loop solvent-based machine.The Site is underlain by alluvial gravel, sand and clay of valley and floodplain areas. Ground water was encountered during the previous investigations at a depth of 18 feet below ground surface (bgs). However, depth to water table following completion of the wells ranged from 12 to 14 feet bgs. The measured groundwater gradient is to the southeast. Between 2003 and 2006, Leymaster and HVN, conducted a Phase I environmental investigation, several rounds of the Phase II environmental investigations, groundwater monitoring events, and remedial actions at the Site. Investigation results indicate that the soil, soil gas, and groundwater beneath the Site have been impacted with volatile organic compounds (VOCs) consisting primarily of tetrachloroethylene (PCE), which is the main chemical used in dry cleaners machine operated at the Site. The highest concentration of PCE at 870 microgram per kilogram (╡g/Kg) was found in a soil sample collected at 15 feet bgs at the vicinity of former dry cleaning machine. The maximum concentration of PCE at 261 microgram per liter (╡g/L) was found in a soil vapor collected at 7 feet bgs at the vicinity of former dry cleaning machine Historical groundwater analytical results also indicated that PCE was detected at maximum concentration of 207 ╡g/L in down-gradient well MW-5. In May and June 2006, HVN, submitted two documents including remediation progress and quarterly groundwater monitoring reports and requested a Site closure providing some justifications described in the remedial action report. Upon the preliminary review of the Site closure report, Regional Board staff discussed requirements for considering Site closure in a project meeting on August10, 2006. In response to the Regional Board?s comments, on November 1, 2006, HVN developed and submitted the Soil and Soil Gas Confirmation Sampling Plan (SCSP) addressing Regional Board concerns. The SCSP was reviewed by Regional Board staff and conditionally approved via email on February 13, 2007 (copy attached). The results of SCSP were discussed with CSWP and CSC during the project meeting on March 18, 2008, concluding the following: ? Adequate, field and laboratory data are collected for soil matrix beneath the Site; ? PCE concentrations in groundwater monitoring wells are near the acceptable limit; however, vertical extent of the impacted groundwater has not been fully defined. Additional investigation and groundwater monitoring program are still required. ? We concurred with CSC?s recommendation for additional soil gas survey, focusing on lateral extent of the PCE vapor plume, and a human health risk assessment to evaluate subsurface vapor intrusion to the indoor air. Follow up project meeting on March 18, 2008,and to address the Regional Board?s comments the Work Plan was prepared by CSC and submitted to the Regional Board on July 22, 2008. Currently the Site is under supplemental investigation to evaluate of the risk to human health for intrusion of subsurface VOCs vapors into indoor air. A soil vapor extraction system operated from January 2005 to June 2006 and from May 2013 to October 2014 at the site. The results of the latest soil vapor and interior sub-slab vapor sampling were used to determine risk to human health from subsurface vapor intrusion into indoor air. The evaluation indicated that the site does not pose a significant threat to the users for a commercial and/or industrial use of the site. based on the results of the investigation and human health risk assessment, the regional Board issued a no further action determination for the site in July 2016. a Covenant and Environmental Restriction was executed and recorded in the Office of the County Recorder of Los Angeles County, State of California on June 29, 2016 to restrict future site use to commercial and/or industrial uses ST.

The formerly Wetherly Cleaners occupied a portion of this multi-tenant building from 1996 to 2006. Currently the Site is unoccupied and the building is under renovation. According to the information provided, five environmental site investigations were conducted beginning in 2003. The investigations included installation of 24 soil borings and three groundwater monitoring wells at the Site. The analytical results confirmed that both soil and groundwater beneath the Site are impacted with Volatile Organic Compounds (VOCs) including tetrachloroethylene (PCE), trichloroethylene (TCE), dichloroethylene (DCE) and others. The findings are consistent with the documented use of PCE at the former dry cleaner. The data show PCE concentrations as high as 942 micrograms per kilogram (╡g/Kg) in soil and up to 1,940 micrograms per liter (╡g/L) in groundwater. Limited soil remediation consisting of excavation and off-site disposal of impacted soil was also conducted at the Site. The maximum depth of the soil excavation was 7.5 feet below ground surface (bgs). The maximum amount of impacted soil was removed without jeopardizing the structural integrity of the building. The soil confirmation data was obtained from bottom and walls of excavation. In addition, a soil gas survey conducted at the Site found mostly a low or no flow condition. The three groundwater monitoring wells were destroyed during the remedial excavation. Based on the post excavation soil matrix and soil gas confirmation data, the Site Mitigation Unit of the County of Los Angeles Fire Department issued a no further action letter for the soil portion of the Site and referred the Site to the Regional Board for further investigation of the groundwater. The Site is located in the Hollywood Basin of the Coastal Plain of Los Angeles. Based on the soil boring log, the soil beneath the Site consists of primarily lean clay up to 18 feet underlain by sand to the maximum depth of investigation of 36 feet bgs. Groundwater was encountered at 19 feet bgs but static water level was measured at 10 feet bgs suggesting that groundwater beneath the Site is under confining conditions. The groundwater flow is to the northeast. * Other Means Multi-Tenant Office-Warehouse Property 1500-1510 West 228th Street Torrance CA Cleanup Program Site Open - Site Assessment Tetrachloroethylene (PCE) Other Groundwater (uses other than drinking water), Soil, Soil Vapor In September 2013, a Phase I Environmental Site Assessment was prepared and identified various industrial land uses including machine shops, manufacturing tenants, auto restoration operations and auto parts manufacturing.

The Site has operated as a custom automotive wheel manufacturing facility for over 15 years. As a part of daily activities at the Site, a film of oil was washed off the wheel rims as a last stage of cleaning in preparation for distribution. The wash solution that was used contained tetrachloroethylene (PCE). This work was accomplished in one bermed area of the building. The coating on the concrete was compromised over the years, and the PCE moved through the concrete, into the soil and then into the groundwater. Several environmental investigations were conducted at the Site, and identified an area of PCE impacted soil around a wash sink where wheel bands were prepared for welding of the decorative wheel center. The results of these investigations found PCE values in soil as high as 308 milligrams per kilogram (mg/kg) at 3 feet below ground surface (bgs). The first saturated zone was found to exist at 16 feet bgs, with a PCE concentration of 42 micrograms per liter (╡g/L) in the shallow groundwater. A remediation work plan was submitted to the Regional Board in 2006 to address the contamination of soil with volatile organic compounds (VOCs). The proposed remedial approach was application of soil vapor extraction (SVE) at the contaminated areas. The system was started up in January 2007. A network of 4 vapor extraction wells (VE1 through VE4) was used for removal of VOCs from the soil. Three of the wells had screen intervals from 2.5 to 6 feet bgs. The fourth well had a screen interval from 4 to 12 feet bgs. A 250 cfm positive displacement blower was used to provide a vacuum of 12 to 22 inches of water at the four well heads. The system operated for approximately one year, after which it was shut down based on the non-detect levels of VOCs registered at the system inlet. A confirmation soil sampling work plan was submitted to Board staff for review in February 2008. After approval of the work plan, the sampling was conducted in July 2008 at 11 locations within a 30-foot radius of the central extraction wells (VE-2 and VE-3). Soil samples were collected at 3, 5, and 7 feet bgs and analyzed for VOCs. PCE was detected in 9 of the 11 locations, with a maximum concentration of 50,100 micrograms per kilogram (╡g/kg) at 5 feet bgs in boring CB-11. No other VOCs were detected in soil. In December 2008 Board staff requested additional groundwater investigation at the Site. Groundwater investigation was conducted at 3 indoor and 2 outdoor locations in September 2009. No contamination of VOCs were detected in the groundwater. In February 2010, Board staff requested additional groundwater sampling within the source area to confirm the quality of groundwater in that area. The results for the additional groundwater sampling was submitted in May 2010 to the Regional; Board. Based on the very low concentrations of PCE in the groundwater it was determined that the PCE contamination has substantially come to a cessation in the upper 5 feet of soil and has had minimal or no migration to the shallow groundwater beneath the Site. As such, a land use covenant (LUC) was issued for the Site and was to be registered by the Orange County Cleck Recorder. According to the LUC, neither the current owner nor any future owner has the right to change the conditons of the Site in such a way that casues the release of the exisitng PCE contamination in soil, into the groundwater. MERCURY CLEANERS 23804 MERCURY ROAD LAKE FOREST CA Cleanup Program Site Open - Remediation Tetrachloroethylene (PCE) Other Groundwater (uses other than drinking water) The site is a former dry cleaning unit (operated from 1981-2004) that has significant contamination of soil and soil gas with PCE. Groundwater contamination is low to moderate. Comprehensive soil and soil gas investigation has been conducted at the Site. The RP has implemented full scale AS/SVE at the Site (June 2014). Off-site downgradient groundwater investigation has been partially completed. Geology: Sediments are typically very fine to fine grained sandy silt. Silt lenses with trace amounts of clay can be found interbedded withing the sandy silt in the upper 45 feet of the vadose zone. Hydrogeology: Groundwater flows north-northwest Depth to Water: 27-30 feet bgs Contamination: PCE is present in soil at concentrations greater that 100 mg/kg in an apprximatedly 21,500 square foot area, at depths between 5 and 30 feet bgs. The extent of groundwater contamination has not been defined. SVE: SVE targets the three permeable zones (caused by interfingering of silts and clays). A: 5-10 feet bgs B: 12-18 feet bgs C: 23-24 feet bgs SVE radius of influence: A: 71-76 feet B: 110-117 feet C: 50-54 feet AS radius of influence A: 98 feet B: 94 feet C: not calculated because of saturation of soil Based on the third quarter soil vapor investigation, highest soil vapor concentrations are present in the deepest screen interval (50-54 feet bgs). Duo to decrease in VOCs concentration a rebound study is initiated in December 2015 based on the approved work plan submitted on December 18, 2015. * Other Means The Orchard Shopping Center, former Silver Cleaners 23684 EL TORO ROAD LAKE FOREST CA Cleanup Program Site Open - Site Assessment Tetrachloroethylene (PCE) Aquifer used for drinking water supply, Other Groundwater (uses other than drinking water) The former Silver Dry Cleaners, which operated for 16 years (1982-1998), was located in Suite "S" (or Suite 698) of the former Saddleback Valley Plaza. Chlorinated solvents, primarily tetrachloroethylene (PCE), were first identified in soil by Hemphill, Green & Associates, LLC (HGA) in November 1999. Soil vapor sampling results from HGA's investigation indicated that PCE was present at concentrations up to 13,000 micrograms per liter (╡g/l) at 2 feet below ground surface (bgs), and 5,700 ╡g/l at 5 feet bgs, beneath the former dry cleaner space. No other volatile organic compounds (VOCs) were detected in the soil vapor samples. Between September 2002 and late 2003, several additional soil and groundwater investigations were conducted in the vicinity of the Site. The bulk of the PCE contamination in both the vadose and saturated zones was centered on the location of the former dry cleaners. The investigations consisted of soil and groundwater sampling from borings that were advanced to depths ranging from 26 to 49 feet bgs. The maximum PCE concentration found in the soil was 370 IJg/kg. The highest concentration of PCE in groundwater was 4,100 !Jg/L (geoprobe location GP-7), found in the footprint of the former dry cleaning facility, while the second highest concentration of PCE in groundwater was detected in a boring located 120 feet east of the tenant cluster (1 ,000 IJg/L at GP-11). In 2005, under the oversight of staff from the Orange County Health Care Agency (OCHCA), England Geoscience (EG) conducted a source area excavation at the Site. Approximately 623 cubic yards of soil were removed by successive excavations, in accordance with the OCHCA- approved cleanup goal of 50 ╡g/kg of PCE. At the completion of the major excavation phase, EG reported that the remedial excavation had succeeded in removing all of the PCE-impacted soil that had been identified at the Site, with the exception of one small, visibly discolored area on the western wall (at 7 feet bgs) of the deepest northwestern portion of the excavation. This residual PCE-impacted soil, which was identified by a sample containing 91 ╡g/kg PCE, was estimated by EG to have a volume of less than 20 cubic feet. Following the remedial excavation, concentrations of PCE in groundwater in the vicinity of GP-7 dropped from a historical maximum of 4,100 ╡g/L (GP-7, 2004) to 44 ╡g/L (monitoring well MW-1, 2012), a greater than 99% reduction. PCE concentrations in the vicinity of GP-11, however, dropped from a maximum of 1,000 ╡g/L (GP-11, 2004) to 280 ╡g/L (MW-3, 4012), only a 70% reduction. On June 5, 2013, Regional Board staff request additional investigation of soil and groundwater in the vicinity of GP-11 and the area between the former dry cleaners and MW-3. We also requested that you investigate the potential existence of a secondary contaminant source zone. In response, the Supplemental Soil and Groundwater Investigation was conducted to further delineate the extent of soil and groundwater contamination in that area in June 2013. In the September 2013 report, we found the following elements of the report noteworthy: ? There is an apparent trend of increasing PCE concentrations in groundwater in the southeastern portion of the Site that may indicate that the plume is migrating offsite. ? Elevated concentrations of PCE (240 ╡g/L) were detected in grab groundwater samples at location GW-30, which is approximately 120 feet cross-gradient of the former dry cleaners, and approximately 60 feet from the Site's eastern property boundary, and a concentration of 150 ╡g/L was detected directly between the former dry cleaners and MW-3. ? PCE was detected in a soil sample collected from the borehole at sampling location GW-29. Based on the additional grab groundwater samples and second quarter 2015 groundwater monitoring event, groundwater flow direction is to the south/southwest with 0.005 to 0.013 ft/ft.

Contamination from this source spreading offsite along the interface of the fill materials and the bedrock (toward lower elevation areas) does not appear likely, based of the non-detection of PCE in areas near the sewer line running from the drycleaner facility, and the main sewer to the west. Furthermore, th~non-detection of PCE in soil samples taken from moist or wet sections (at 21.5' bgs) of the soil column in 3 boreholes suggests that the zone of saturation had thus far not been impacted. Because the release was apparently minimal--centered around the facility's drycleaning machine, and shown to not have migrated to lower elevation areas--and did not appear to have impacted saturated soils, it was proposed that the impacted shallow soil be left in place. To determine if leaving the contaminated soil in place would be justified, OCHCA conducted a vapor risk assessment based on site conditions and the highest PCE concentration detected: the calculated excess lifetime cancer risk (ELCR) was acceptable, i.e., less than the maximum allowable ELCR of 1.0 E-06.

CARRIAGE TRADE CLEANERS - BROOKHURST PLAZA 17209 BROOKHURST STREET FOUNTAIN VALLEY CA Cleanup Program Site Completed - Case Closed Tetrachloroethylene (PCE) Under Investigation Tetrachloroethylene (PCE) was present in soil and groundwater at the Site, as a result of past activities at the Carriage Trade Cleaners. The responsible party conducted soil excavation at the Site in March and April 2004, after the strip mall had been demolished. Soil excavation was conducted according to a soil cleanup goal of 50 ╡g/kg. The remedial excavation was backfilled, and a Sam?s Club store was constructed on the property. PCE concentrations in the groundwater at the Site had recently decreased to below the detection limits for PCE. The results from the first quarter of 2009 groundwater monitoring showed no detection of any VOCs in the groundwater in wells MW-1 and MW-2. Monitoring wells MW-1, MW-2, and MW-4 were sampled on July 16, 2009. Groundwater analytical results did not show detection of chlorinated VOCs in any of the wells. A soil vapor sample was also collected from the vapor probe installed next to well MW-4 on July 16, 2009. No detection of VOCs was shown in the analytical results. Based on the groundwater monitoring results, and the fact that the downgradient area has no detection of chlorinated VOCs in the groundwater, it appears that the Site does not represent a threat to the beneficial uses of groundwater in the Orange County Groundwater Management Zone of the Santa Ana River Watershed. Additionally, based on the results from the confirmation soil sampling, a significant amount of the contaminant mass has been removed from the soil at the Site. The remaining mass of PCE in the south excavation wall does not appear to be a threat to the quality of the shallow groundwater. Also, based on the results from the recent and previous soil vapor sampling at the Site, PCE is not present at concentrations that would present any threat to human health. Therefore, no further action is required with respect to soil and groundwater at the former Carriage Trade Cleaners ? Brookhurst Plaza at 17209 Brookhurst Street in Fountain Valley, California. This NFA determination is based on available information, with the provision that the information that was submitted to Board staff was accurate and representative of Site conditions. * Other Means BRISTOL SHOPPING CENTER - FORMER 1-DAY CLEANERS 3825 SOUTH BRISTOL STREET SANTA ANA CA Cleanup Program Site Completed - Case Closed Tetrachloroethylene (PCE) Other Groundwater (uses other than drinking water) The site is a former dry cleaner with significant soil contamination with PCE and very low contamination of groundwater. Excavation of the soil in the indoor areas had been conducted to the extent possible. However, upon further investigation of the adjacent tenant units and the outdoor areas it was determined that soil is also contaminated in these areas. Soil excavation has been requested in these areas. Additional sampling for optimizing the area to be excavated was conducted and the final boundaries of the excavation area was determined. A revised work plan for soil remediation was approved in December 2011. Plan for soil excavation was approved by the City of Santa Ana after a sanitary sewer line located within the excavationa area was relocated. Excavation via large diameter auger (LDA) began in August 2013 and completed in September 2013. Verification monitroing of the perched groundwater is ongoing at the Site.

However, these initial investigations have not been able to determine how far the PCE may have migrated since it was released. Soil gas investigations that were conducted in 2013 and early 2014 detected the presence of elevated concentrations of PCE in the soil vapor beneath the dry cleaners, adjacent units of the shopping center, the alley behind the shopping center, and the parking area of the Sienna Pointe apartments. Mitigation of the soil vapor intrusion risk is a driving factor in the selection of remediation technologies and is the current focus of work at the Site.

Soil samples collected in 1999 were reported to have detectable concentrations of volatile organic compounds (VOCs) including tetrachloroethene (PCE) and trichloroethene (TCE). These results documented that a discharge of chlorinated hydrocarbon wastes from the dry cleaning equipment had occurred. Centro Properties Group (Centro) conducted soil and groundwater investigations and delineated the soil, soil vapor, and groundwater plumes associated with the discharge. Between 2004 and 2006, Centro conducted cleanup activities, including excavation and off-site disposal of VOC-bearing soil and operation of a soil vapor extraction/air sparge system to remove VOCs from soil and groundwater. In May 2013 the on-site building was demolished and contaminated soil was excavated. The site was then redeveloped to include a new commercial building located outside the area of soil impact and a soil vapor barrier was installed to minimize migration of soil vapors into the building. A new well (MW-6) was installed within the excavation footprint and was found to contain elevated concentrations of PCE. MW-6 is currently undergoing 2 years of quarterly sampling.

Subsurface Monitoring PRP INVESTORS MADISON, LLC 3492, 3500 MADISON STREET RIVERSIDE CA Cleanup Program Site Open - Site Assessment Tetrachloroethylene (PCE) Soil, Soil Vapor Site Description The Site is composed of three parcels comprising approximately 7.1 acres of partially developed commercial land located within a mixed commercial and residential area in the city of Riverside, California, within the Riverside-D Groundwater Management Zone (GMZ). The Site is bounded to the southwest by single family residences, to the northwest by apartment buildings, to the northeast by Madison Street with restaurants and stores beyond, and on the southeast by the California Route 91 Freeway, followed by commercial developments beyond. The Site is currently developed with three commercial buildings and a large asphalt parking area. Two additional buildings were located on the southwestern portion of the Site, but were demolished between 2005 and 2007. Historical records indicate the demolished buildings (3492 and 3500 Madison Street) had been occupied by dry cleaning facilities from before 1966 until at least 1981. Previous Investigations Several Phase I Environmental Site Assessments have been conducted for the Site. In 2003, ALTA EM identified potential petroleum fuel impacts to the soil and groundwater beneath the Site originating from the gas station immediately adjoining the Site to the east. ALTA EM also found that a portion of the Site (3500/3502 building) had been occupied by a dry cleaners and indicated that there was a moderate to high likelihood that the former dry cleaning operations had created a recognized environmental condition on the Site. They recommended that a soil gas survey be completed in all areas possibly occupied by the former dry cleaning operation. A second area (3486 building) was identified as having been occupied by a dry cleaning operation from 1985 to 1992. Despite being described as a ?drop zone only? with no dry cleaning plant, ALTA EM recommended that the soil survey be extended to this area as well because ?numerous vent pipes of possible suspicion were also detected in this same area.? The ALTA EM report was followed up two years later, in 2005, by a second Phase I ESA produced by SECOR. SECOR found that based on quarterly monitoring reports, it was not likely that petroleum fuel from the adjoining gas station was impacting soil or groundwater at the Site. SECOR also referenced a Soil Sampling report prepared by Ceres Associates in June 2003 that involved collecting a total of ten soil samples at a depth of one foot below ground surface (bgs) from the vicinity of 3492/3494 and 3500/3502 Madison Street. This report has not been submitted to the Board, but according to the SECOR Phase I report, low to non-detectable concentrations of VOCs were identified in the soil samples. SECOR recommended further sampling to test for the presence of VOCs at greater depths. In November 2005, SECOR advanced 6 soil borings to a depth of 10 feet bgs in the areas of the Site which were once occupied by dry cleaning facilities. Soil samples were collected from 2, 5, and 10 feet bgs. Soil vapor samples were collected from a depth of 7 feet bgs at each of the boring locations. Laboratory analyses of the soil samples reported reported concentrations ranging from 2-27 ╡g/kg of tetrachloroethene (PCE). Soil vapor samples reported concentrations ranging 15-22 ╡g/L of PCE and 1.8 ╡g/L of chloroform. The soil vapor concentrations are above the ESLs for land in commercial use. SECOR concluded that additional investigation was warranted because the vertical and horizontal extents of the VOC vapor impacts were not defined during the initial investigation. Additional soil and soil vapor sampling was reported by SECOR in May 2007, based on the recommendations of their 2005 report. SECOR advanced 8 additional soil borings in the vicinity of previous soil sampling locations near the location of former dry cleaning operations. Three borings were located near 3492 Madison Street and 5 were located in the vicinity of 3500 Madison Street. Each boring was advanced to a total depth of ten feet bgs using a GeoProbe 5400 drill rig and soil samples were taken at five foot intervals (5 and 10 feet bgs). The soil gas sampling string was constructed by driving a steel rod and expendable drive tip into the soil starting at a sampling depth of 7 feet bgs, dislodging the expendable tip, connecting ╝-inch poly-tubing to the bottom of the steel rod, and finally connecting the poly-tubing to a vacuum pump. Samples were taken by connecting an empty Tedlar bad to the vacuum pump and pumping gas from the subsurface into the Tedlar bag. The results of the 2007 sample analyses showed lower contaminant concentrations than the 2005 sampling event. Soil samples reported concentrations of PCE ranging from non-detectable to 3 ╡g/kg, while soil vapor concentrations ranged from 2.0 ╡g/L to 25 ╡g/L. It appears that samples were taken using post-run tubing, samples were drawn through poly-ethylene tubing and the vacuum pump before being captured in the Tedlar bags, and samples collected in Tedlar bags were analyzed more than 6 hours after the samples were taken. Each of these factors can cause artificially low contaminant concentrations to be detected due known problems with leakage and sorption of COCs to sampling equipment. These methods are not recommended by the Board. However, based on the low concentrations of PCE found in shallow soils and failure to detect PCE in soil samples taken from 10 feet bgs, SECOR concluded that soil contamination was limited to depths between 2.5 and 4 feet and that soil vapor impacts were a result of the shallow impacts. Furthermore, based on sampling data from both Phase II investigations, SECOR concluded that two source areas exist: one approximately 25 feet by 15 feet to a depth of 4 feet and located in the vicinity of B-2 and SB-3 (the southeastern wall of the former 3500 building) and the other approximately 15 feet by 15 feet to a depth of 4 feet bgs located in the vicinity of SB-6 (the southeastern wall of the former 3492 building). Based on the findings and recommendations of the Continued Phase II investigation, in May 2007 SECOR prepared a work plan to excavate the two source areas. Although the work plan was subsequently accepted by the County of Riverside Department of Environmental Health (DEH), the work was never performed. The next environmental assessment did not occur until six years later, when in February 2013, IWS Environmental, Inc. (IWS) conducted a Phase II Environmental Assessment?Limited Soil Gas Survey with the intent to determine the extent of PCE in soil vapor under the footprint of a proposed Wal-Mart store at the Site. IWS advanced 10 soil probes to a depth of 10 feet with sample collected at 5 and 10 feet bgs and at one boring location at 4 and 7 feet bgs. Borings were located throughout the footprint of the proposed building. Soil samples were not taken as part of this investigation. IWS collected samples with a gas-tight, glass syringe and analyzed samples onsite with a GC/MS configured in series to target VOCs in accordance with EPA method 8260B. PCE was detected at all but three of the ten sampling locations. In many cases, higher concentrations of PCE in soil vapor were detected at 10 feet bgs than at 5 feet bgs. Two sampling events were performed in September 2013 and 2014. Results are presented in October 3, 2014 report. A HHRA was submitted for the site under various scenarios and ILCR Values and HQ was estimated. The results are presented in November 4, 2014 report. A request for no further action was submitted in March 2015 followed by another HHRA evaluating various scenarios for sensitive receptor. This HHRA was requested following intent of site developers to built a fitness club that includes a child care center. The Water Board has requested another soil vapor sampling from the foot print of the fitness club and currently is evaluating issuing NFA under Land Use Covenant (LUC) for this site. The resultsof the soil vapor sampling conducted on November 12, 2015 showed lower range of PCE compared with previous results (0.24-1.1 ug/L for MVP-1 and 0.055-0.14 ug/L for MVP-3). An LUC is in preparation and review for this site. INLAND EMPIRE CLEANERS 6266 VAN BUREN RIVERSIDE CA Cleanup Program Site Completed - Case Closed Tetrachloroethylene (PCE) Other Groundwater (uses other than drinking water) The site is a former dry cleaners facility with PCE release to the soil and groundwater. PCE contaminated soil was removed in July 2003. Maximum PCE concentration left in soil was 32 ug/kg. Groundwater monitoring was initiated in August 2003. Groundwater monitoring was stopped in 2004 and resumed in 2008. Further assessment for the groundwater in the downgradient area was conducted in March 2009. However, a complete vertical delineation of the PCE contamination in the groundwater was not performed despite the requests from the Regional Board. Therefore, a request for site closure was denied in August 2009. Additional monitoring well installation in the downgradient area of the Site was conducted in November and December 2010. Very low to non-detect cocnentrations of PCE were detected at the new monitoring wells. It was determined that no further investigation and/or remediation for the Site is needed at this time. The SIte was put on a semi-annual groundwater monitoring as of February 2011. After the review of the groundwater monitoring reports for 2Q11, 4Q11 and 2Q12, it was determined that the PCE impact in soil is no longer a threat to human health and beneficial uses of the groundwater in the Arlingtom GMZ. An NFA letter was issued on August 21, 2012.

PCE was released on the ground surface during the dry cleaner's operations, which ceased in the 1980s. Sampling results from a related investigation indicate that the property is a possible source of PCE - impacted groundwater in the area. Regional Water Board staff have supervised two phases of a soil vapor and groundwater investigation in the Stockton Blvd - Fruitridge Road area, including this site. Results of these investigations suggest that the Site is a source of PCE impacts to groundwater and soil vapor. TOWN & COUNTRY SHOPPING CENTER 2601 MARCONI AVE SACRAMENTO CA Cleanup Program Site Open - Remediation Tetrachloroethylene (PCE) Aquifer used for drinking water supply A dry cleaning business known as Village Cleaners operated at what is now 2601 Marconi Avenue from 1947 through 1986 before moving to an adjacent parcel at 2709 Marconi Avenue, Suite B where it has continued to operate through the present.

AFFINITO PROPERTY 4943-5039 FOLSOM BLvd SACRAMENTO CA Cleanup Program Site Open - Verification Monitoring SACRAMENTO COUNTY LOP Tetrachloroethylene (PCE) Other Groundwater (uses other than drinking water) A Phase I and Limited Phase II Environmental Assessment was conducted in 1997. The study identified three primary concern areas. First, a potential lead-contaminated soil issue related to a neighboring clean-up project to the west (former body shop). Second, a potential dry-cleaning solvent issue related to an on-site cleaner. Third, typical fuel tank concerns relative to the former gas station portion of the property. Research and a limited Phase II investigation found no conspicuous problems with the former gas station which has supported a tire shop and used car sales since removal of the fuel tanks apparently during or before the early 1980s. There is an existing oil/water separator or waste oil tank near the former gas station building, and it is planned that this be removed under County oversight prior to redevelopment of the property.An investigation conducted in 2000 confirms elevated lead concentrations on the northeasterly corner of the subject property and indicated that subsurface soil samples collected near the cleaners contained low levels of PCE. The cleaners tenant moved out in December 1997. A small, antique furniture dealer 'presently occupies this portion of the building. A monitoring well to a depth of 40-feet below grade surface (bgs) was installed. During the drilling work, relatively undisturbed soil samples were collected at depth of 15-, 20-, and 30-feet bgs. Following the drilling work, the boring was fitted with a two-inch diameter PVC well casing. Of the three soil samples collected from the monitoring well boring, the upper two tested "clean." The 30-foot deep sample revealed a trace of PCE at a concentration of 0.051 parts-per-million (ppm). The testing of the groundwater (measured at a depth of 29.3-feet bgs the week after drilling) revealed a PCE concentration of 720 parts-per-billion (ppb). These findings indicate that, at the monitoring well location, the soil above is not impacting shallow groundwater. Rather the impacted groundwater is the source of the PCE found in the 30-foot deep sample. Based upon this, prior site data and information regarding the westerly neighboring remediation site, it can be concluded that there is an impact to groundwater and that the source has not been clearly determined. Based on the groundwater analytical results, the County, in a letter dated May 18, 2001, requested the submission of a workplan to define the extent of PCE at the site. On June 18, 2001, a workplan proposing the installation of three additional groundwater monitoring wells was submitted. These wells would help to laterally define the extent of PCE in groundwater and one deep soil boring to vertically define the extent of PCE in soil in the source area. In a letter dated June 26, 2001, the County conditionally approved the workplan requesting additional analysis of 1,4-Dioxane by Method 8270 from the deepest soil sample collected from boring SB-Deep and all the water samples. In July 5 and 6, 2001, installation of three 2-inch diameter groundwater monitoring wells (MW-2 through MW-4 occurred). All three wells were completed to a total depth of 40 feet bgs. One soil boring was completed to a depth of 60-feet bgs (SB-Deep) to assess the vertical extent of contaminant migration in soil in the former source area. -In September 2001, consultants supervised the excavation of lead-impacted soils. On October 2, 2001, the consultants supervised the removal of a steel 1,000-gallon waste oil underground storage tank (UST), one steel 500-gallon waste oil UST and one concrete oil/water separator. On October 3, 2001, the consultants supervised the excavation of the former sewer line that served the former site building. The entire length of the former sewer line, which was buried approximately five feet bgs was removed. On October 31, 2001,one 4-inch diameter soil vapor extraction (SVE) well (VEW-1) was installed. On November 6, 2001, eight piezometers located in three clusters (P-lthrough P-3)were installed. On November 12, 2001, the consultants conducted the first five-day SVE pilot extraction test. Analytical results from soil gas samples collected during the SVE test indicated declining concentration of PCE. The PCE concentration initially was 760 micrograms per liter (ug/L) (approximately 110 ppmv) and decreased to 390 ug/L (approximately 58 ppmv) at the end of the pilot test. Extraction rates varied from 4.2 pounds per day (Ib/day) PCE initially, to 2.2 Ib/day, at the end of the test. The total PCE extracted during the test is estimated at approximately 13.8 pounds. Radius of influence calculations were calculated during this test and ranged from 59 feet in the shallow subsurface to 246 feet in the smear zone. On February 27, 2002, a second five-day SVE test was initiated at the site. Analytical results from soil gas samples collected during the SVE test indicated the PCE concentration initially was 440 ug/L (approximately 65 ppmv) and declined to 110 ug/L (approximately 16 ppmv) at the end of the pilot test. Extraction rates varied from 3.5 Ib/day PCE initially, to 0.9 Ib/day, at the end of the test. The total PCE extracted during the test is estimated at approximately 10.1 pounds (20.6 pounds total for both 5-day tests). On March 14, 2002, a third five-day SVE test was initiated at the site. Analytical results from soil gas samples collected during the SVE test indicated the PCE concentration initially was 130 ug/L (approximately 19 ppmv) and declined to 85 ug/L (approximately 13 ppmv) at the end of the pilot test. Extraction rates varied from 0.7 Ib/day PCE initially, to 0,5 Ib/day, at the end of the test. The total PCE extracted during the test is estimated at approximately 3.0 pounds (23.6 pounds total for both 5-day tests). On March 8, 2002, Apex introduced 110 pounds of potassium permanganate into the groundwater at the site. Permanganate is an agent that oxidizes organic compounds containing carbon-carbon double bonds such as PCE.The County issued a letter on June 20, 2002 requesting a workplan for the installation of an additional well.The consultants performed a soil gas survey to define the plume on July 24, 2002. On December 2, 2002, Sacramento County Environmental Health Department (SCEHD) issued a response to the Workplan conditionally accepting the proposed additional well. One groundwater monitoring well. was installed. PCE at the site is not yet defined.

Former McKenry One Hour Cleaning 6325 Fair Oaks Boulevard Carmichael CA Cleanup Program Site Open - Site Assessment Tetrachloroethylene (PCE) Aquifer used for drinking water supply, Soil, Soil Vapor Various dry cleaning businesses operated at the property between approximately 1965 and 2000, including Payless Cleaners, One Hour Martinizing Cleaners, Wool?s One Hour Martinizing Clothing Cleaners, and McKenry One Hour Cleaning. These businesses used tetrachloroethylene (also known as perchloroethylene, perc or PCE) in their dry cleaning process. Site assessments conducted at the adjacent ARCO site have detected PCE in groundwater at concentrations up to 960 micrograms per liter, with the highest concentrations in the monitoring well located closest to the former McKenry Dry Cleaning property (ARCO MW-5). PCE has also been found in soil vapor beneath the ARCO site at concentrations up to approximately 5,700 parts per billion by volume (about 39,000 micrograms per cubic meter). These results were collected during the course of investigation of a gasoline station fuel release and were not intended to define the extent of PCE impacts to soil, soil vapor, or groundwater in the vicinity of the site. Soil and groundwater samples have previously been collected at the former McKenry Dry Cleaning property in 2001. PCE was detected in soil samples at depths between 4 and 28 feet at concentrations ranging from 0.0008 to 0.97 milligrams per kilogram. A single groundwater sample was also collected beneath the property at a depth of 150 feet and did not contain detectable PCE. However, the groundwater sample was collected significantly deeper than the shallowest first-encountered groundwater and therefore could have missed sampling an on-property discharge of PCE to shallow groundwater. Soil vapor and first-encountered groundwater samples have not been collected beneath the former McKenry Dry Cleaning property. California Department of Public Health records indicate concentrations of PCE in the two closest municipal wells to the site, which are owned by the Carmichael Water District. Sunrise Village Retail Center (Former Dry Cleaner) 7837 Madison Avenue Citrus Heights CA Cleanup Program Site Open - Remediation Tetrachloroethylene (PCE) Soil, Soil Vapor Sunrise Village Retail Center, LP operated the Sunrise Cleaners, a dry cleaning facility located at 7837 Madison Avenue, Citrus Heights, Sacramento County (Site). Historical operation of a dry cleaner at the Site resulted in the presence of volatile organic compounds (VOC?s), including tetrachloroethylene (PCE) in soil and groundwater beneath the Site. The Site is located in a large multi-tenant retail shopping center located on approximately 12 acres of land known as the Sunrise Village Retail Center. The existing shopping center was first constructed circa 1975. Significant Site operations appear limited to a dry cleaning facility that operated in the same tenant space from 1977 to 2010. Regulatory agency records confirm that this onsite dry cleaning facility included the storage and use of the industrial cleaning solvent perchloroethylene (PCE) during this time period. The dry cleaning facility is no longer operating onsite although some equipment and materials remained in the tenant space until 2014. Historical use of the subject Site prior to construction of the existing shopping center generally included a rural residence and vacant undeveloped land back prior to 1937. There are several nearby former gasoline station sites located approximately 500 feet to the east of the Site with a history of soil and groundwater impact that have received case closure under the LUST program from the regulatory agency.

GOSS-JEWETT FACILITY (former) 4301 POWER INN ROAD SACRAMENTO CA Cleanup Program Site Open - Remediation Tetrachloroethylene (PCE) Other Groundwater (uses other than drinking water) Goss-Jewett was a laundary and dry-cleaning chemical supply company that operated from the late 1960's to 1996 at 4301 Power Inn Road, now occupied by The Matress Factory. The property was owned by Mr. Edward Anselmo from 1976 to October 1995, when it was sold to Mr. James Kotrous. On 4 January 1996, Sacramento County Environmental Management Department and the City of Sacramento, Division of Hazardous Materials inspected the site and found approximately 100 55-gallon drums in various stages of decay. An aboveground storage tank contained tetrachloroethylene (PCE) used as a dry-cleaning solvent. The PCE dispenser did not have a nozzle, and according to the Sacramento County incident report, it appeared that PCE had leaked onto the ground. On 20 January 2000, the District Attorney negotiated separate plea agreements with Goss Jewett, which included a $100,000 fine and probation, and Mr. Lamanet, which included a $25,000 fine and probation. The Regional Water Board issued Cleanup and Abatement Order No. R5-2002-0707 (CAO), on 2 May 2002, along with Monitoring and Reporting Program No. R5-2002-0801. On 13 June 2003, the Regional Water Board amended the CAO to provide an agreed upon schedule for assessment and remedial work in CAO No. R5-2003-0702. As of September 2010, these Orders remain in effect. PCE contaimination was fouind in the soil beneath the PCE storage tank and in other areas of the drive at the rear of the facility. Groundwater monitoring found PCE up to 17,000 ug/l beneath the former storage tank. The MCL for PCE is 5 ug/l and the Water Quality Objective for PCE is 0.06 ug/l. Remedial measures include excavation of soil beneath the tank, soil vapor extraction and operation of a dual-density circulation well (DDC) and air-sparging in one monitoring well. PCE in the groundwater has decreased to under 20 ug/l beneath the storage tank. However, monitoring well MW-2, slightly upgradient from the source area, continues to contain about 200 ug/l of PCE. * GOV, Facility Inspection, Site Assessment/Site Investigation, Visual Sacramento Co.

The city of Victorville acquired the property from the County for redevelopment in 2007. Phase I and II Environmental Assessments performed by the United States Environmental Protection Agency (USEPA) Targeted Brownfield Contractor in 2009 identified chlorinated solvents, primarily tetrachloroehtene (PCE) in soil gas samples. The greatest concentrations were found in the vicinity of floor trenches within the building and along the southwest wall of the building. USEPSA conducted indoor air sampling of nearby buildings. Concentrations of PCE above indoor guidance values were measured in the basement of the school district administrative building to the southwest of the site. Hot spot removal was conducted by USEPA in the vicinity of floor trenches within the building and along the southwest wall of the building. The removal consisted of excavating and disposing of approximately 195 cubic yards of contaminated soil during 2010. Ninyo and Moore installed a soil vapor extraction system (SVE) that operated from September 2010 through July 2011 that removed 540 pounds of PCE. Following hot spot removal and the SVE remediation, USEPA found concentrations of PCE within the acceptable guidance values. In November of 2014 Ninyo and Moore conducted a groundwater investigation that detected PCE, with the greatest concentration being found northeast of the site. The concentrations of PCE reported during the quarterly monitoring have continued to show and increasing trend through 2015. Water Board staff learned in September 2015 that a tailor shop was associated with the NuWay Dry Cleaners. The Tailor Shop was located to the southeast of the cleaners, immediately across the alley. Ninyo and Moore conducted a soil gas survey during January and February 2016 that included the Nuway Dry Clearers parcel and the associated Tailor Shop parcels. Concentrations of PCE were found on all three parcels, with the greatest concentrations being detected near the center of the Nuway Dry Clearers parcel.

Site is located at 9755 Distribution Avenue, San Diego, California, the property is 2.12 acres parcel of land (APN 343-100-26). On or about June 15, 1975, the original owners of the site, Nicholas and Hronopoulos, entered into a 10 year lease agreement with Goss-Jewett Company for the Sunflower site. Goss-Jewett was in the business of receiving, selling and distributing perchloroethylene (PCE), a solvent typically used in dry cleaning operations. The PCE contamination at the site resulted from Goss-Jewett's operations between June 1975 and December 1990. Detectable concentrations of PCE in soil vapors ranged from 1.9 to 8444 mg/l. The highest concentrations of PCE in soil vapor were detected at sample points SV-11 (8444 mg/l), and SV-12 (7579 mg/l), located adjacent to the train loading dock on the south side of the site structure. Soil sampling consisted of installing two soil borings in the area where the greatest concentrations of PCE in soil vapors were detected north of the site structure, near the truck loading dock (at sample point SV-2, PCE was detected at 6431 mg/l). PCE concentrations in the soil from the borings were as high as 10,059,000 mg/kg at B-2, (at 2 feet) and 248,863 mg/kg at B-1 (at 2 feet). On June 19, 1997, a technical report was prepared by Dames & Moore and submitted to DTSC. Consequently, on July 24, 1998, DTSC issued an Imminent and Substantial Endangerment (I&SE) order to the Responsible Parties (RPs) to clean up the site. On June 24, 2003, DTSC approved the final Remedial Action Plan (RAP) for the soils operable unit (OU1) and asked the RPs to start investigation on the groundwater & VOCs operable unit (OU2). On June 10, 2005, the RPs submitted the well installation report. On August 4, 2005, the RPs submitted the updated Groundwater Monitoring report. The San Diego Regional Water Quality Control Board was the Lead Agency for the groundwater issue for investigation and remediation and they transfered it back to DTSC on Jan. 2011. DTSC is following up with the RPs and cosultant to complete vadose zone characterization for VOCs, to stop the downward migration of VOCs and to remediate the entire vadose zone.

Mad Engine 9393 WAPLES ST SAN DIEGO CA Cleanup Program Site Completed - Case Closed SAN DIEGO COUNTY LOP Tetrachloroethylene (PCE) Soil The site consists of a relatively small area of impact (approximately 500 to 1,000 square feet), which is part of a large commercial property. The area around the site is dominated by large commercial buildings in the City of San Diego just north of Carroll Canyon. From 1995 to 2004, the site building, in the area of the release, was being utilized by Mad Engine for silk screening. A spot remover containing tetrachloroethene (PCE) was used to remove excess ink from items during the silk screening process. Two 55-gallon drums of the spot remover were observed at the site by the consultant during an environmental investigation. The property owner entered the County of San Diego, Voluntary Assistance Program (VAP) to oversee investigation activities related to PCE-impacted soil observed during phase II activities. Several borings were installed at the site to evaluate potential soil and soil vapor impacts. Assessment activities at the site focused on volatile organic compounds (VOCs), the primary constituents of potential concern in the spot remover. Only PCE was detected in soil with a maximum concentration of 330 micrograms per kilogram. The majority of observed PCE impacts in soil existed between approximately five and ten feet below building slab grade. The consultant concluded that PCE-impacted soil was adequately assessed and estimated that approximately 430 cubic yards of PCE-impacted soil exists at the site. While low levels of 1,2,4-trimethylbenzene and xylenes were observed in soil vapor samples, PCE was not detected above the laboratory reporting limits in soil vapor. The consultant estimated that groundwater was located greater than 100 feet below grade based on available information from sites in the vicinity and ground surface topography. The consultant concluded that groundwater was adequately protected due to the vertical extent of PCE-impacted soil being limited to approximately 10 feet below building slab grade and the estimated depth to groundwater of greater than 100 feet below grade. The consultant recommends that the case be closed. Based on the provided information, the Department of Environmental Health, Site Assessment and Mitigation Program concurs with the consultant. Site Assessment/Site Investigation Phase II property assessment Business closed down FRAME MARITAL TRUST 8655 COMMERCE AVENUE SAN DIEGO CA Cleanup Program Site Open - Site Assessment SAN DIEGO COUNTY LOP Tetrachloroethylene (PCE) Soil, Soil Vapor On May 5, 2011, DEH received a Limited Phase I and Phase II Site Assessment Report in conjunction with an application for the Voluntary Assistance Program, and case H02503-001 was opened. The report described the current and former use of the site and summarized the results of soil vapor sampling inside and outside the building on site. The site consists of a building constructed in the mid-1970?s which is currently, and has been historically occupied by commercial dry cleaners. Soil vapor samples were obtained from ten locations at one foot below ground surface (bgs). Tetrachloroethylene (PCE) was detected in all soil vapor samples at concentrations of 3,500 to 91,000 micrograms per liter (ug/l) and trichloroethylene (TCE) was detected in five of the soil vapor samples at concentrations of 23-49.6 ug/l. The consultant concluded that a PCE release had occurred on site, which appears to have been located near the dry cleaning machines in the central portion of the property. The consultant states that additional environmental site assessment operations will be necessary to determine the extent of the release. DEH concurred with the consultant?s conclusions. However, the levels of PCE in the soil vapor samples indicate a health risk to the occupants of the building on site. As such, DEH directed the responsible party to prepare an Interim Remedial Action Plan (IRAP) to mitigate the health risk from PCE vapors. DEH determined that additional site assessment, including delineation of the extent of PCE-impacted soil and investigation of potential impacts to groundwater are necessary, and that a workplan describing the proposed assessment should be submitted to DEH for approval prior to performing additional site assessment. DEH recommended that soil borings be completed to a minimum of 50 feet bgs or until PCE and TCE are not detected in two consecutive soil samples. DEH was informed that the building is currently vacant on May 23, 2011, and as a result DEH determined that the IRAP does not need to be completed until the building will be occupied. DEH approved a Site Assessment Work Plan on June 21, 2011. The consultant proposed drilling seven borings; four inside the building to 19 feet and three outside the building to at least 50 feet. Soil samples will be analyzed for chlorinated volative organic compounds. The borings will be completed as monitoring wells if groundwater is encountered.

ONE HOUR DRY CLEANERS 115 JAMACHA RD EL CAJON CA Cleanup Program Site Open - Site Assessment SAN DIEGO COUNTY LOP Tetrachloroethylene (PCE) Aquifer used for drinking water supply, Soil, Soil Vapor Two Phase II Environmental Site Assessment reports were completed in 2004 and included soil sampling and analysis inside the building adjacent to the dry cleaning machine and in the boiler room, and outside to the northwest of the building on site. Tetrachloroethylene (PCE) was detected at up to 11,000 micrograms per kilogram (ug/kg) adjacent to the dry cleaning machine. DEH received a request for review of site assessment documents and Voluntary Assistance case number H33964-001 was opened on November 3, 2008. DEH required additional site assessment to delineate the extent of PCE contamination in the soil, investigate potential impacts to groundwater, and address the risk from PCE vapors to occupants of the building on site. Additional soil sampling was completed around the dry cleaning machine in the suite occupied by the dry cleaning operation and the adjacent suite to the north, which is occupied by a salon. Based upon all soil sampling completed on site, the consultant concluded that the extent of PCE-impacted soil was limited and at shallow depths. DEH concurred with this conclusion and determined that the extent of PCE-impacted soil had been assessed. DEH also directed that a monitoring well be installed adjacent to the dry cleaning machine to assess groundwater and that the heating, ventilation, and air conditioning (HVAC) system be evaluated due to the unacceptable vapor risk to building occupants indicated by the soil sampling results. A monitoring well was installed adjacent to the dry cleaning machine in August 2010; however, DEH determined that the screen was incorrectly placed in the well and that an additional groundwater monitoring well was required. DEH also required that sub-slab vapor sampling and a human health risk assessment be completed, as well as the previously requested evaluation of the HVAC system. A workplan to complete these activities was approved by DEH on May 2, 2011.

This section will be updated as data is received. FORMER AZTEC CLEANERS - CENTREPOINT DEV. 6319 EL CAJON BOULEVARD SAN DIEGO CA Cleanup Program Site Completed - Case Closed SAN DIEGO COUNTY LOP Tetrachloroethylene (PCE) Soil The site consists of an approximately 20-foot by 100-foot vacant, unpaved lot that was formerly occupied by Aztec Cleaners. The lot is located within the former College Center shopping mall. The Aztec Cleaners building and the shopping complex buildings have mostly been demolished to allow for construction of a proposed multi-family residential development (Centrepoint). Past environmental assessment activities at the former dry cleaners site, including soil borings and soil vapor sampling, showed that tetrachloroethene (PCE) releases had occurred from the dry cleaning equipment. The site assessments were conducted in 2003 to 2004 under VAP case numbers H00296-001 and H39702-001. DEH closed those cases based on mixed residential and commercial use, but included a closure restriction. The restriction states that the area of the site with known PCE contamination must be redeveloped as a paved entrance way, and no inhabited residential or commercial space is allowed to be built over the PCE-impacted soil, even when the area is paved. This VAP case (#H00296-002) was opened to provide DEH oversight of the excavation and off-site disposal of the remaining PCE-impacted soil at the site to allow for unrestricted residential and commercial use of the property. The known contaminated soil was located in the southern portion of the site, and the maximum reported PCE concentration was 1,100 micrograms per kilogram (╡g/kg) in a soil sample collected at a depth of five feet below ground surface (bgs). Reported PCE concentrations in the other soil samples collected during the 2003/2004 site assessment ranged from less than 5 ╡g/kg (the laboratory reporting limit) to 45 ╡g/kg. The maximum PCE concentration detected in soil vapor samples collected at a depth of 5.5 feet bgs at eight on-site soil boring locations was 10 micrograms per liter (╡g/l). The calculated cancer risk was reported to be 1.9 X 10-07, which is less than the accepted threshold of one-in-one-million. In accordance with a DEH-approved workplan dated April 27, 2012, the environmental consultant excavated the PCE-impacted soil, collected soil confirmation samples from the sidewalls and the base of the excavation, and disposed of the soil at a licensed disposal facility. The soil excavation activities were conducted in October and November 2012, and the final depth of the excavation ranged from approximately six to twenty-six feet bgs. A total of approximately 2,846 tons of PCE-contaminated soil was trucked off-site to the South Yuma County Landfill facility in Yuma, Arizona. Based on the depths of previously-reported contamination, sidewall confirmation samples were collected along the perimeter of the excavation at approximately 30-foot increments, and bottom confirmation samples were collected at a frequency of approximately one every 400 square feet. PCE concentrations in all of the confirmation soil samples were less than 5 ╡g/kg, with one exception. A PCE concentration of 11 ╡g/kg was reported at a depth of 19 feet at one location, but the location was overexcavated to a depth of 20 feet, and PCE was not detected in two confirmation samples collected less than 10 feet away at a depth of twenty feet bgs. Based on the completed remedial excavation activities at the site, the consultant concludes that the site is suitable for residential use without restrictions, and recommends no further action with respect to the presence of PCE in soil at the site. DRY CLEAN 4 LESS 199 N EL CAMINO REAL ENCINITAS CA Cleanup Program Site Open - Site Assessment SAN DIEGO COUNTY LOP Tetrachloroethylene (PCE) Soil Vapor DEH received an application for the Voluntary Assistance Program along with a Risk Assessment Report on April 17, 2006. The report summarized the results of soil sampling and air sampling on site. Sampling was initiated due to a fire at the site in 2003 which damaged the dry cleaning machine, resulting in a release of tetrachloroethene (PCE). After the fire, a new dry cleaning machine was installed that does not use PCE. Four soil samples were collected at depths of 2 and 5 feet below ground surface (bgs) from soil borings adjacent to the dry cleaning machine and down-gradient. PCE was detected at 280 micrograms per liter in one soil sample, which was collected at 2 feet bgs inside the building adjacent to the dry cleaning machine. The consultant also collected two air samples from inside the building, and PCE was not detected in the air samples. Based upon these results, the consultant concluded that there was no health risk from PCE vapors. The consultant also concluded that since groundwater in the area is not beneficial and there are no sensitive receptors within 0.5 miles, the risk to the environment from the release is minimal. The consultant recommended that the case be closed. DEH reviewed the file in August 2011, as the case has been inactive since 2006. The SAM Vapor Risk Model was used to estimate the cancer risk from PCE vapors, which was 5.96 x 10-6. Since this exceeds the DEH threshold of 1 in 1 million, the cancer risk is not acceptable. As a result, DEH can not close the case unless it is demonstrated that the PCE release does not pose a health risk. Towards that end, soil vapor sampling is necessary. Note that the air sampling previously completed is not valid as the guidelines for air sampling in the SAM Manual were not followed. A minimum of four vapor probes are required within the general area of the dry cleaning machine with a minimum of two soil vapor sampling events over a 2-3 week period. DEH recommends that a workplan be submitted to DEH for review prior to commencing soil vapor sampling. Property Sale/Transaction SOIL SAMPLING PCE NO LONGER USED ON SITE WHITE CLEANERS (former) 2829 24th St Oakland CA Cleanup Program Site Open - Remediation Tetrachloroethylene (PCE) Other Groundwater (uses other than drinking water), Soil, Soil Vapor Former dry cleaner. From 1996 to 1999, several investigations were completed at the site to evaluate soil and groundwater quality. Elevated concentrations of halogenated volatile organic compounds (VOCs), specifically the dry cleaning solvent PCE, were detected in soil and groundwater during these investigations. The approximately 2,400-square-foot building reportedly was constructed in the 1920s and was occupied by White Cleaners, a laundry and dry cleaning establishment, from approximately 1953. The site is located within a larger 0.23-acre lot occupied by commercial and residential structures. Three groundwater monitoring wells (MW-1, MW-2, and MW-3) were installed at the Site in January 1997. In December 1997, approximately 41 tons of impacted soils were excavated from an area to the south of the building, and 700 gallons of impacted groundwater containing separate phase solvent product were pumped from the excavation. During the excavation work, and during previous site investigations, a concrete slab was encountered at an approximate depth of 3.5 fbg beneath the building and the area immediately to the south of the building. In the area to the south of the building, the slab was observed to transition to a lower tier approximately 4 feet in width and approximately 6 fbg. The upper portion of the slab appeared to slope toward this lower tier, which essentially formed a below grade containment sump. It appeared that the slab had acted as at least a partial barrier to the downward migration of contaminants. The excavation was backfilled with drain rock and two 4- inch diameter slotted pipes (OW-1 and OW-2) were installed in the sump area for future monitoring purposes. In November 2004, three offsite exploratory borings (EB-8 through EB-10) and seven offsite monitoring wells (MW-4 through MW-10) were installed. In October 26, 2005, one additional deep groundwater monitoring well (MW-11) was installed onsite. A well survey was completed in 2004. The well survey area covered an area 1,000 feet downgradient (southeast) of the Site, based on the established groundwater flow direction, and 500 feet in the upgradient and crossgradient directions. No documented irrigation/potable wells were identified in the well study area based on the available records.In June 2007 an ozone sparge (OS) and soil vapor extraction system (SVE) was installed to remediate PCE impacted soil and ground water beneath the site and to help reduce the PCE concentration of vapors that were migrating into the onsite nearby structures.. Nine (9) CPT borings were advanced in October 2008 to depths ranging from 44 to 60 fbg. Based on the grab groundwater data collected during this investigation, and on the historical trends observed in Site monitoring wells during quarterly monitoring and sampling events, the dissolved phase plume is adequately defined both laterally and vertically. The OS system was turned off in 2014. Currently (2016), the SVE system is operating and maintained to assist in further decreasing PCE concentrations in soil vapor and to serve as a mitigation measure to limit vapor intrusion into nearby structure.

STOCKTON CA Cleanup Program Site Open - Remediation Tetrachloroethylene (PCE) Soil The first site development was construction of a gasoline service station on the northeastern corner of Pacific Avenue and Robinhood Drive in the late 1960s to early 1970s. The building that houses the dry-cleaning facility was later constructed in the early to mid-1980s. A dry-cleaning facility has been present at the location indicated on Figure 2 since construction of that building in the early to mid-1980s. The Site is currently occupied by the Robinhood Plaza Shopping Center. Hazardous substances are stored and used at only a few tenant spaces, including C&S One Hour Martinizing facility, and Smilecare (dentistry). Mr. Charles Patel, the owner of C&S One Hour Martinizing, has operated the drycleaning business at this location for approximately 19 years. Mr. Patel informed LFR?s representative that he stopped using PCE approximately 5 years ago and began using a silicone-based solvent produced by GreenEarth Cleaning. According to information provided by GreenEarth Cleaning, the silicone-based solvent is an odorless, non-volatile organic compound that breaks down into water, carbon dioxide, and sand. This material is stored in two cylinders located on the side of the drycleaning machine. Mr. Patel noted that the filters in the cylinders are replaced approximately every six months. The filters are removed from the Site by Technichem and disposed of as hazardous waste as a precaution to address the possibility that clothing previously cleaned at other dry-cleaning facilities could contain PCE.

No concentrations were included in the documentation. The Stockton Warehousing & Industrial Center (SWIC) site (Global ID T0607700196) is a closed UST case adjacent to the property. The SWIC case file states that it was formerly identified as 4648 East Waterloo Road (same address at this property). In 1988, on 550-gallon underground storage tank (UST) was removed from the SWIC site. Several investigations were conducted and the UST case was closed by San Joaquin County Environmental Health Department (SJEHD) on 28 October 2011. SWIC monitored the domestic well and 1,2-DCA was not detected above laboratory detection limits. The investigations conducted at the SWIC site (which appears to be the same address as this property) are sufficient to close the Site. Drinking water in the area is provided by the City of Stockton municipal wells and no wells are located within 2,000 feet of the property.

The subject Property is a rectangular shaped parcel located on the southern comer of the intersection of Laurel Street and Morse Boulevard, in San Carlos, San Mateo County California. The building was reportedly built in 1945. The building is constructed on a concrete slab with no basement and was utilized as a marker until 1976. From 1976 till September 2001 the northern portion of the building was occupied by Carlos' Dry Cleaners. Dry cleaning equipment that utilized PCE was used onsite. Since that time the building has been extensively remodeled. Currently a chiropractic office and an allergy clinic occupy the southern portion of the building (lease spaces I and 2). A drop off location for Carlos Dry Cleaners occupies the northern portion of the building (lease space 4). No active dry cleaning activities occur at this location. Lease space 3, the area where former dry cleaning operations occurred, is currently occupied by an urologist office. The subject property is at approximately 25 feet above mean sea level on a gently sloping plain that dips eastward to Oakland Bay. The United States Geologic Survey (USGS) has mapped the area as Quaternary alluvial deposits that have been eroded off the Santa Cruz Mountains that rise to the west. Based on previous investigations. subsurface site soil consists of gravel till immediately underneath the concrete slab to an approximate depth of 8 inches. Below the gravel fill, a grayish brown. silty clay was encountered to an approximate depth of 8 to 10 feet. Based on visual observation it is anticipated that this material will exhibit Ion. permeability and will yield water at a slow. rate. Below the clay, silty sand, sand and gravel sediments were encountered. These coarse grained units were saturated and rapidly yielded water. Static groundwater was encountered ar a depth of approximately 4 feet. The shallow clay yielded water slowly. The lower coarse grained sediments readily yielded water. which rises rapidly indicating confined conditions. Regional groundwater flow is to the northeast, concurrent with the trend of the regional topography. PIERS completed a Phase I Environmental Site Assessment (ESA) for the subject property in March 2002. PIERS concluded that with the exception of the use of the dry cleaning equipment and PCE there are no other environmental concerns regarding the Property. Because of this concern PIERS conducted a Phase I1 investigation in March 2002 that consisted of shallow soil sampling in and around the dry cleaning machines as well as a drain outside the building (maximum depth explored 2.5 feet). Seven soil samples were collected and five samples analyzed for PCE and other volatile organic compounds (VOCs) by EPA Method 8010. PCE was detected in the four soil samples collected from the interior of the building. No other chemicals were detected. In May 2002, AllWest performed a subsurface investigation that consisted of advancing four geoprobe borings (B1 through 84). Eight soil samples and three groundwater samples were analyzed for VOCs and naphtha. PCE was detected in shallow soil samples with concentrations decreasing with depth. PCE along with two of its breakdown products were detected in the groundwater samples. Naphtha was not detected in any of the samples collected. Based on the results of the investigation, AllWest concluded that historic operations in the vicinity of the dry cleaner had resulted in the release of PCE and recommended that furthe1 characterization of the lateral extent be performed. In June 2002 EnviroVision, Inc. advanced 13 soil borings (SB- 1 through SB- 13) both inside and outside of the building and collected soil and groundwater samples for VOC analysis. Results of the investigation documented that concentrations of PCE in soil decreased with depth. PCE was detected in all groundwater samples submitted for analysis. Various PCE breakdown products were also detected in some of the water samples. EnviroVision recommended additional sire characterization to further define the extent of PCE in soil and groundwater. In addition. they also proposed an interim remedial action. Consisting of excavating soil containing elevated levels of PCE from the interior of the building. In September 2002 EnviroVision oversaw the excavation of approximately >6 cubic yards of soil from the interior of the building near the location of the former dry cleaning operation. Soil was excavated to a depth of approximately 5.5 feet where groundwater was encountered. 13 confirmation soil samples were collected from the sidewalls and bottom of the excavation. Approximately 150 gallons of water were removed from the excavation. A "grab" groundwater sample was collected from the excavation after recharge. Soil and groundwater samples were analyzed by an on-site laboratory. PCE was detected in all soil and groundwater samples collected from the excavation. After sampling approximately 60 pounds of a hydrogen release compound (HRC) was poured into the excavation. HRC was added to the subsurface to stimulate anaerobic microbial growth which in turns enhances the rate of biodegradation of chlorinated solvents. The excavation was then backfilled with a 3/8 inch gravel from the bottom of the excavation to an approximate depth of 2 feet. Graded sub-base was placed over the gravel and the cement floor was replaced. EnviroVision concluded that PCE concentrations detected in the confirmation sample were below risk based screening level (RBSL) for commercial use. Additional groundwater characterization was recommended. In December 2002, SOMA Corporation prepared a human health risk assessment for the facility. The purpose of the assessment was to "evaluate the appropriateness of future tenant occupancy" and provide supporting documentation for site closure. Based on maximum concentrations of PCE in soil a site specific evaluation of the risk for the indoor air inhalation pathway was performed. The result of the assessment indicate that the cancer risk did not exceed a one in a million and the "PCE in soil does not appear to propose a risk of adverse public health effects for tenant occupancy by a urologist using the premise for his practice." The SMCHSA, in a February 2003 letter, approved occupancy of the lease space by the urologist.

FASHION CLEANERS 336 WOODSIDE PLAZA REDWOOD CITY CA Cleanup Program Site Open - Site Assessment SAN MATEO COUNTY LOP Tetrachloroethylene (PCE) Other Groundwater (uses other than drinking water) Extracted from AllWest's August 8, 2005 Subsurface Investigation and Conduit Assessment and December 12, 2008 Site Characterization Report, San Mateo County does not take responsibility for the accuracy of the statements made or any professional interpretations made in the referenced report. Redwood Shopping Plaza is located in a mixed residential and commercial area of Redwood City on the west side of Woodside Road. The subject property is bound by residences to the north and west, retail businesses to the south and Woodside Road and retail businesses, including a dry cleaner and Shell station, to the east. Historical research indicates the subject property was vacant and undeveloped prior to construction of the existing shopping center in the 1950s. A Union gas station was present on the subject property from approximately the 1960s to the early 1990s. Historical documents indicated the presence of dry cleaners at the subject property from at least the 1960s. The subject property is currently developed with eleven single-story commercial buildings which comprise approximately 171,832 leaseable square feet. The surface topography of the site is relatively flat, sloping gently to the northeast. In November 2002 MACTEC performed a Phase and Phase II investigation of the subject property. A Phase III investigation was completed in January 2005. To evaluate on and off-site environmental concerns, MACTEC reviewed a site specific Environmental Data Resources, Inc. (EDR) report which reviewed agency lists/databases for recorded sites within the industry standard search radii. The subject property, specifically Fashion Cleaners and Helen?s Cleaners, were listed on the RCRIS-SQG, and HAZNET databases. The Union gas station formerly present at the subject property (1500 Woodside Road) was listed on the ERNs, LUST, Historical UST and Cortese databases. MACTEC indicated that no information was available concerning former UST removals at the facility, but that the facility received regulatory case closure in May 2000. MACTEC also reviewed records concerning the Shell station, 1667 Woodside Road, located immediately east-southeast of the subject property across Woodside Road and listed on the LUST database. MACTEC?s review of the County records indicated that soil vapor extraction and groundwater extraction and treatment systems were operating at the site as a result of discovered soil and groundwater contamination. Quarterly groundwater monitoring results from 2004 indicated that concentrations of TPHg and MTBE of 300 and 3.7 ppb, respectively were present in a well approximately 120 feet northeast of the subject property. MACTEC concluded that the onsite extraction system was effectively capturing contaminated groundwater and there was a low likelihood that the subject property would be affected by the Shell station. Several other sites in the subject property vicinity were listed on environmental databases; however, based on distance, groundwater gradient and/or site status considerations, none of these sites are likely to have impacted the subject property. Based on the long-term historical operation of dry cleaning facilities on the subject property, MACTEC performed a Phase II assessment in the vicinity of the dry cleaners in November 2004. Two soil borings were advanced to a maximum depth of approximately 31 feet below ground surface (bgs) in close proximity to Fashion Cleaners and Helen?s Cleaners. Samples were collected at approximately 5-foot intervals and screened for the presence of organic vapors with an organic vapor meter (OVM). A grab groundwater sample was also collected from each boring. One soil sample from each boring near the soil/groundwater interface was retained for analysis. The soil and groundwater samples were analyzed for volatile organic compounds (VOCs). The results of analysis indicated the presence of PCE in the soil and groundwater samples collected near Fashion Cleaners at concentrations of 5.8 and 100 ppb, respectively. PCE was detected in soil and groundwater from the boring near Helen?s Cleaners at 810 and 1400 ppb, respectively. No other VOCs were detected. Based on the results of the previous soil and groundwater survey, MACTEC performed an additional investigation at the subject property in January 2005. The investigation included collection of soil, soil vapor and grab groundwater samples from nine borings advanced on the subject property. All samples were analyzed for the presence of VOCs. Soil analyses did not identify PCE in any of the samples. Trichloroethene (TCE), a degradation product of PCE, was detected in one sample and duplicate sample. In groundwater, PCE was detected in four borings at concentrations ranging from 0.72 to 44 ppb. No other analytes were detected in groundwater. Concentrations of PCE in groundwater were below the Regional Water Quality Control Board (RWQCB) environmental screening level (ESL) for PCE of 120 ppb, but, with one exception, were above the U.S. EPA drinking water maximum contaminant level (MCL) of 5 ppb. Analysis of soil gas samples, which were collected from depths of 1, 5 and 10 feet bgs indicated the presence of PCE, benzene, ethylbenzene, toluene, xylenes and 1,2,4-trimethylbenzene. Except for the PCE, the detections were consistent with petroleum hydrocarbons. Detected levels of these chemicals were below applicable screening levels. Detected concentrations of PCE ranged from 860 to 70,000 micrograms per cubic meter (ug/m3), with the highest concentrations detected adjacent at Fashion Cleaners. Levels detected at both dry cleaning locations were above the ESL of 1,400 ug/m3 for commercial/industrial use. MACTEC also performed a sensitive receptor survey for the site, which identified one monitoring well within 1/8 mile downgradient of the subject property with the potential to be affected by the onsite contaminant plume. However, because the well was not a drinking water well, MACTEC concluded that it was unlikely that the onsite contamination would affect drinking water. Investigation activities conducted between August and November 2008 including a sensitive receptor survey, soil sampling via geoprobe, semi-permanent soil vapor probe installation and sampling and lastly, groundwater well construction, development and sampling. Thirty-five soil samples were collected from six geoprobe and four monitoring well borings. Six ?grab? groundwater samples were collected from geoprobe borings. Groundwater samples were collected from each of the four monitoring wells; vapor samples were collected from each for the four sub-slab soil vapor points. levels exceeding corresponding ESLs. Fashion Cleaners appears to have experienced a smaller PCE release as exhibited by lower soil and groundwater contamination levels and aerial extent of impacted area. Soil vapor data was unusable due to high concentrations of ambient air. Helen?s Cleaners has a larger area of PCE impacted soil and groundwater. Groundwater contamination originating from this location has likely migrated off-site across Woodside Road. Sampling data scheduled to be collected from the Shell Station will provide further insight to plume characteristics. Soil vapor levels exceeded the ESL at Helen?s. Quarterly sampling of installed vapor probes will provide data to further assess initial sample results. Previous investigations at the property indicate sub-surface utility lines are unlikely preferential pathways for the movement of groundwater due to their relatively shallow depth. Soil vapor sampling data collected at Helen?s Cleaners indicate PCE concentrations detected in a vapor sample is likely due to the movement of the gas through adjacent sewer lines. Quarterly monitoring of the soil vapor probes will provide additional data to further assess soil gas migration away from the release source area. AllWest updated a sensitive receptor survey conducted in 2004 for the adjoining Shell gas station by conducting additional field research. The subject site?s PCE release will not impact identified sensitive receptors in the area. * SA 855 MALCOLM ROAD 855 MALCOLM ROAD BURLINGAME CA Cleanup Program Site Completed - Case Closed SAN MATEO COUNTY LOP Tetrachloroethylene (PCE) Soil * Other Means TRANSFER FROM LOCAL AGENCY DUE TO INACTION OF PROPERTY OWNERS 39-49 El Camino Real 39-49 El Camino Real Millbrae CA Cleanup Program Site Open - Inactive Tetrachloroethylene (PCE) Indoor Air, Other Groundwater (uses other than drinking water), Soil, Soil Vapor The site is a multiple unit commercially developed building; a former dry cleaning operation existed in the area of the site that is currently used as an asphaltic paved parking lot.

Two (2) groundwater monitoring wells installed into the shallow aquifer underlying the site (30 ft bgs); MW-1 up to 15,000 ug/L of PCE; P-11 soil sample at 3 ft bgs contained 660 ug/kg of PCE. Residual PCE remains in shallow soils and groundwater beneath the site that is most likely a result of previous site use (dry cleaner). An active gasoline station and underground storage tank (UST) investigation site located two parcels to the southeast at the intersection (western corner) of Millbrae Avenue and El Camino Real (5 El Camino Real). There is a monitoring well (MW-16) located on the subject site related to this nearby UST investigation. Sampling of that well has resulted in the detection of non-petroleum hydrocarbon related constituents PCE (1,000 ug/L) and TCE (26 ug/L).The local groundwater gradient during 1/2012 monitoring was very flat (0.009 ft/ft) in a southeast direction (S49E). 9/2012 groundwater monitoring results: MW-1 22,000 ug/L of PCE; MW-16 740 ug/L of PCE and 21 ug/L of TCE.

The Site is part of the 7.6-acre Borel Square Shopping Center owned by the Borel Estate Company. The shopping center includes two single-story buildings with a total of approximately 92,629 square feet in commercial space. Current occupants include a grocery store, several restaurants, and several retail facilities. The Site is located in the approximate center of the shopping center. The shopping center is bounded to the east by South El Camino Real and Highway 92 to the south, and is located in a suburban setting characterized by commercial office and retail development along with single- and multi-family residential development. The shopping center was developed on the subject parcel in 1967 prior to which it had been occupied by a church since 1940s. Full-service dry cleaning operations have been conducted at the Site since the shopping center was constructed in 1967. The current operator has been onsite for approximately eight (8) years. The dry cleaning process was recently upgraded to incorporate the use of eco-friendly cleaning solvents. Prior to the upgrade, the dry cleaning process utilized tetrachloroethene (PCE), a dry cleaning solvent, in a closed loop system. The PCE was stored in a chamber in the dry cleaning machine. Upon completion of the cleaning cycle, the PCE was recycled via carbon filters and a built-in still. The machine was sealed during the cleaning cycle to prevent emissions to the atmosphere from the stack and the discharge of vapors into the building. The vapors were condensed for reuse at the end of the cleaning cycle. The dry cleaning machine was underlain with a steel secondary container in order to prevent spills onto the concrete flooring. Approximately 75 gallons of PCE were used by the dry cleaning machine per month. The impurities were accumulated as sludge from the recovered and condensed fluid. The sludge was removed on an as-needed basis and placed in a properly labeled and sealed 35-gallon drum, stored behind the dry cleaning machine. The sludge and spent filters were removed on a periodic basis by Technichem, Inc. for proper disposal. Previous Site investigations include: �� Phase II Soil and Groundwater Investigation. �� Phase I Preliminary Site Assessment. �� Phase I Environmental Site Assessment (ESA). �� Phase II ESA. �� Phase II Remedial Investigation. �� Soil Vapor Survey. �� Remedial Action Plan. �� Soil Vapor Extraction Implementation Report. �� Development of Target Cleanup Goals and Request for Closure Sampling. Based on the existing information regarding local geology obtained from the previous investigations, the Site is situated on the alluvial plain that extends along the margins of the San Francisco Bay and, regionally, is underlain by thick alluvial deposits. The Site is underlain by fill material (sand, silt, and gravel) to a depth of approximately 2 or 3 feet below ground surface (bgs). The fill material is underlain by silty clay with rounded gravel pebbles to depths of at least 43 feet bgs. Although static groundwater levels in the existing five monitoring wells range from approximately 12 to 17 feet bgs, none of the groundwater monitoring wells are screened across a common interval. Therefore, a groundwater gradient and direction could not be determined from the historic data. Based on previous Site characterization data, soil vapor extraction (SVE) of VOCs was implemented as the selected remedial action. SVE system operation is currently ongoing. The SVE system consists of four extraction wells (SVE-16 through SVE-19) located in the vicinity of the dry cleaning machine. The extracted vapors are treated using two carbon canisters in series with treated vapors discharged under a permit from Bay Area Air Quality Management District (BAAQMD). The SVE system currently operates daily for six hours. Monthly monitoring of system parameters includes flow rate and photoionization detector (PID) readings as a measure of VOC concentrations at the inlet and the outlet to the carbon filters. Quarterly SVE reports are provided to GPP to document system performance and PCE mass removal. Detailed information on SVE system design and operation is provided in the SVE Implementation Report.

The Site was used for laundry cleaning until the 1970's where it shifted into a dry cleaning operation. Since the mid 80's the Site has been vacant. There is a building on the Site which is currently not utilized. The latest groundwater/ soil information was collected in 1998 and 1999. The analysis focused on metals and VOCs in soils and VOCs in groundwater. Arsenic ESLs are exceeded in shallow soils with a commercial/industrial screening and groundwater used for drinking water purposes. PCE, TCE, cis-DCE, VC ESLs are exceeded with similar screening site use scenario. PCE concentrations are as high as 640 ppb in groundwater. Piezometers are installed at the Site. Their adequacy for sampling purposes is unknown. There are no permanent groundwater monitoring points. The highest VOCs detections are found near a sump and sanitary sewer areas. It is the consultant position that off site contamination may have contributed to the groundwater impacts as detected near the sanitary areas. In May 2000, Water Board staff approved a mitigation plan (which has not been implemented) consisting of excavating X cubic feet of soil to a depth of 30 feet bgs. A site management plan, an updated health and safety plan and schedule for off-site are missing from the record. Full groundwater delineation has not been completed. A risk assessment dated March 2000, estimated the total excess cancer risk to 3x10E-7 for off site residents and 6X10E-8 for off site workers. The Site is slatted for mixed use redevelopment to include condos above businesses and a 3 levels garage (including one level at -10 feet bgs grade). However, as of July 2008 it is unclear if the current building will be razed in the near future. It is against city policy to tear down a building and leave a vacant lot.

The subject site consist of a rectangular shaped parcel measuring approximately 25 feet by 100 feet in plan area. The site is developed to its boundary limits with a single-story structure. The site is bound by cit sidewalk and Broadway on the southwest, an asphalt-paved alley onthe northeast, a city-owned landscaped area and asphalt-paved parking lot on the southeast and by an immediately-adjacent structure (Sixteen Mile House restaurant) on the northwest. The site was previously used as a Citibank branch and recently has been modified and improved to operate as a real estate office. The site has its main entrance at the south corner of the building along Broadway and a rear access door at the east corner of the building along the alley. A Phase I Environmental Site Assessment (ESA) performed by Hillmann Environmental Group (HEG) in 2003 identified that the site was historically used as a laundromat with dry-cleaning machine in the 1960?s. During a review of files at the City of Millbrae Building Department, PSI located a site plan for the former ?Betty Brite Coin-O-Mat? located at the subject address, dated June 16, 1964. The site plan showed the locations of an existing (at that time) drycleaning unit (Detrex C-0-6-1) and the proposed location for a second cleaning unit (Prosperity 6-A). The historic plan indicates that the facility had the same basic building footprint as the current structure, however the Broadway entrance was more centrally located on the southwest wall and there used to be a door on the southeast side of the building, facing the parking lot. No door at the alley is noted in the historic site plan. It is not known at this time whether the building was remodeled to the current configuration, or was demolished with a new structure built in its place. HEG performed a Phase II subsurface investigation to assess soil and groundwater conditions due to the presence of the former dry-cleaning machine(s). The Phase II investigation included the drilling of three hydraulic push borings (P1 through P3) with P1 located on Broadway in front of the subject bank building and P2 and P3 drilled in the alley at the rear of the building. Borings P1 and P3 were advanced to 11 feet below ground surface (bgs), while P2 was advanced to 16 feet bgs. Soil at the site consisted of interlayered silty sand and clay, with groundwater encountered at approximately 8 feet bgs in each of the borings. The HEG report stated that groundwater flow was expected to be towards San Francisco Bay (to the northeast). Soil samples were collected for chemical analyses at 10 or 11 feet bgs in Borings P1 through P3. Groundwater was also first encountered at approximately 8 feet bgs and collected for chemical analyses from each of the three borings. The soil and groundwater samples were analyzed for volatile organic compounds (VOCs) by Cal Tech Environmental Laboratories according to EPA Method 8260B. The results of the analyses indicated that PCE was detected only in the soil and groundwater samples collected from boring P2 at concentrations of 0.21 milligrams per kilogram (mg/kg) and 760 micrograms per liter (∞g/l), respectively. Trichloroethene (TCE) was also detected in the P2 groundwater sample at a concentration of 18 ∞g/l. HEG recommended that additional investigation be completed at the site. PSI performed a utility survey in June, 2004 with identified utility locations. Underground utilities at the site include water, electric, gas, and sewer lines. In conversation between PSI and Mr. Martin Creane of the City of Millbrae Streets Department it was stated that the exact depth of the sewer line going into the building was unknown, but it would not be deeper than the main line that runs along Millbrae Avenue (approximately 5 feet bgs). In a conversation between PSI and Mr. Kenneth Huo of the City of Millbrae Building Department it was stated that water, electric, and gas lines are typically not below 5 feet bgs. During the meeting between PSI and Mr. Huo, a site plan was found dated, June 16, 1964, of the former Betty Brite Coin-O-Mat located at the subject address. This plan shows the location of what appears to be a current (at that time) dry-cleaning unit (Detrex C-0-6-1) and the proposed location for a second cleaning unit (Prosperity 6-A). It is not known whether the proposed Prosperity unit was ever installed. The sewer line entering the building is located on the southern portion of the building, while the former dry-cleaning units are on the eastern portion of the building. Based on a groundwater depth of approximately 8 feet, utility lines in the upper 5 feet of soil, the lack of utility lines in the immediate area of the dry-cleaning units, the discontinued use of the dry-cleaning machine, and the lack of contaminants in the groundwater sample from HEG Boring P1 (located next to the sewer line), PSI concluded that the utility lines at the site do not appear to be a current conduit for migration of contamination in the saturated or unsaturated zone. PSI advanced three borings on December 22, 2005; Boring B-1 was advanced adjacent to the former boiler room and Borings B-2 and B-3 were advanced in the locations of the former Prosperity and Detrex dry-cleaning Units, respectively. Soil samples were collected for chemical analyses from all the borings and a groundwater sample was collected from Boring B-3. Borings B-1 and B-2 were only advanced to approximately 5-feet bgs due to equipment limitations relating to ceiling height restrictions. The analytical results indicated the following: ? At Boring B-1, PCE was only detected in the soil sample from the 4 feet bgs (0.036 mg/kg) and not from the shallow soil sample collected at 0.5 feet bgs. ? PCE was detected in both soil samples from Boring B-2 (0.027 and 0.072 mg/kg PCE at 0.5 and 3.5 feet bgs, respectively) in the location of a second, possible (?proposed Prosperity 6-A?) former dry cleaning unit. ? The highest concentrations of PCE detected during this investigation, and the only TCE detected in the samples collected, were from beneath the former Detrex dry cleaning unit at Boring B-3. PCE was detected in soil in Boring B-3 to the maximum total depth of 16 feet bgs. The maximum concentration of PCE in Boring B-3 was at 4 feet bgs at 1.7 mg/kg, with all other six soil samples containing 0.025 mg/kg or less PCE. The grab groundwater sample obtained from Boring B-3 contained 140 ∞g/l PCE. Due to limitations of the drilling equipment and inability to obtain groundwater samples at B-1 and B-2, subsequent work was warranted. The objective of the investigation was to determine if PCE is present in soil and groundwater beneath likely sources at the site, and if present, to evaluate the vertical extent of PCE and its breakdown products in soil. On September 20, 2006, three interior soil borings were advanced. Two borings were proposed, however due to no soil recovery from Boring B-1A, a third boring (B-1B) was advanced adjacent to Boring B-1A. The location of Borings B-1A and B-1B were chosen to be close to the location of previous Boring B-1, near the former boiler room. The location of Boring B-2A was chosen to be close to the location B-2, near the former proposed Prosperity dry cleaning unit. Boring B-1A was advanced to 13 feet bgs and Borings B-1B and B-2A were advanced to 19 feet bgs by Precision Sampling Inc. at the direction of PSI. Based on the report, near surface soil consisted of up to 1 foot of medium to olive brown gravelly sand or sandy gravel underlain by interbedded medium to olive brown silty sand and sandy or clayey silt with dark brown silty clay at the bottom of each of the (deeper) borings. Groundwater stabilized inthe borings at approximately 7 feet bgs prior to grab groundwater sample collection. Six soil samples were collected from Boring B-1B, near the former boiler room. The three shallow soil samples collected to a maximum depth of 10.5 feet bgs did not report detected concentrations of PCE. The highest PCE concentration detected in the boring was at 13.0-13.5 feet bgs at 0.024 milligrams per kilogram (mg/kg). Minor concentrations of PCE were detected to the bottom of the boring at 0.0058 mg/kg (14.0-14.5 feet bgs) and 0.0073 mg/kg (18.0-18.5 feet bgs). Seven soil samples were collected from Boring B-2A, near the former ?proposed? Prosperity dry cleaning unit. Only the two shallowest soil samples reported detected concentrations of PCE; the lower five samples collected between 8 and 19 feet bgs reported concentrations below the laboratory method reporting limit of 0.002 mg/kg. The maximum concentration of PCE (1.1 mg/kg) was reported in the shallowest sample collected at 3.5-4.0 feet bgs. In addition, TCE was detected in this soil sample (3.5-4.0 feet bgs) at 0.048 mg/kg. The sample at 5.0-5.5 feet bgs in Boring B-2A contained 0.32 mg/kg PCE. During advancement of Boring B-2A, PCE (solvent) odor was noted on the boring log and photoizonization (PID) detector readings were recorded up to 74 parts per million (ppm) at 6 feet bgs. Grab groundwater samples were collected from each of the three borings (B-1A, B-1B and B-2A) after groundwater stabilized to approximately 7 feet bgs and reported PCE concentrations of 180, 220 and 22 ∞g/L, respectively. PSI concluded that the highest concentration of PCE detected in soil was from Boring B-2A in shallow vadose zone soils, indicating a likely release source from the ?proposed? Prosperity dry cleaning unit historically located in the area of B-2A. PSI also concluded that the highest concentration of PCE detected in groundwater at the site is located in the alley behind the facility and is likely the result of either plume migration to the east over the last 40 years, or due to historic spent dry cleaning solvent dumping practices. Shallow soil impact by PCE above the Environmental Screening Levels (San Francisco Regional Water Quality Control Board, February 2005) protective of vapor intrusion into buildings (above 0.24 mg/kg for commercial and above 0.087 mg/kg for residential) has been identified at the former locations of the dry cleaning machines at locations B-2A and B-3. The highest concentrations of PCE detected in groundwater are present in Boring B-1B (220 ∞g/L) and previous Boring P2 (760 ∞g/L advanced on May 1, 2003) which are both located towards the east or northeast of the former dry cleaning areas in the inferred direction of groundwater flow. The vapor sampling probes (SV-1 through SV-4) were initially proposed by PSI in the Addendum to Subsurface Vapor Investigation Work Plan and TOXICHEM installed the probes with the modification of moving SV-3 approximately 5 feet west as suggested in the SMCHD letter dated November 20, 2006. Initially during the December 8, 2006 sampling event, four sub-slab soil vapor samples were collected from immediately beneath the floor slab of the building. Representative concentrations ranged from 130,000 ∞g/m3 PCE (SV-3) to a high of 910,000 ∞g/m3 PCE (SV-1 located at the former Detrex dry cleaning unit location). All sub-slab soil vapor samples contained concentrations of PCE above the commercial and residential ESL. Additionally TCE was detected above the residential ESL in probes SV-1 (at 1,600 ∞g/m3) and SV-2 (at 1,400 ∞g/m3 and at 1,500 ∞g/m3 in the laboratory duplicate of SV-2). Following the communication testing event performed between February 15 and 17, 2007 (described later in this report) three vapor points were resampled (SV-1, SV-3 and SV-4). Vapor probe SV-3 was reported to contain 10,000 ∞g/m3 PCE and no (<62 ∞g/m3) TCE and vapor probe SV-4 was reported to contain 8,300 ∞g/m3 PCE and no (<62 ∞g/m3) TCE. SV-1 locatedin the back office near the center of the building contained 370,000 ∞g/m3 PCE and 960 ∞g/m3 TCE on March 7, 2007. Due to preferential flow from the rear of the building observed during the initial communication testing, a second vent location was completed near SV-1 (E-2) and second communication test performed. To aid in communication testing influence, a fifth vapor probe (SV-5) was installed near the west front corner of the building within the utility room. In order to facilitate carpet installation and building occupancy, the existing above-ground completion probes SV-1 through SV-4 were then destroyed and replaced nearby with flush-mount (or recessed) vapor probes (SV-1R through SV-4R). Additionally, the original extraction vent (E-1) near SV-2 was destroyed and a second vent (E-2) was completed near the original SV-1 probe location completed for future use by installing a threaded cleanout-style 2-inch diameter PVC fitting covered by a brass floor plate through the carpet. Two 8-hour indoor air samples (IA-1 and IA-2) and one 8-hour ambient air rooftop sample (OA-1) were collected on February 6, 2007. Both indoor air samples reported concentrations of PCE at 12.0 ∞g/m3. Indoor air sample IA-1 located centrally within the building also contained 0.18 ∞g/m3 TCE, though no TCE was detected (<0.16 ∞g/m3) in the IA-2 sample collected towards the rear of the building. The outdoor ambient air sample was reported to contain 0.64 ∞g/m3 PCE (0.63 ∞g/m3 PCE in the laboratory duplicate). All results (including the outdoor background ambient air sample) were reported above the residential indoor air screening level (ESL) for PCE of 0.41 ∞g/m3 and just below the commercial indoor air screening level (ESL) for PCE of 0.68 ∞g/m3. The concentrations of the constituents in the indoor air samples were all greater than the concentration reported in the outdoor ambient air sample. Subtracting the ambient background air concentration of 0.64 ∞g/m3 PCE from the indoor air concentrations yields results of 11.4 ∞g/m3 PCE for each of IA-1 and IA-2. These results are above both the residential and commercial indoor air screening levels (Table E-3 of the RWQCB ESLs) of 0.41 ∞g/m3 and 0.68 ∞g/m3, respectively. Since both the subslab soil vapor results and the indoor air sampling data are above the ESLs, mitigation is warranted. * SA Stanton Road Associates 860 Stanton Road Burlingame CA Cleanup Program Site Completed - Case Closed Tetrachloroethylene (PCE) VOC contamination including tetrachloroethene (PCE) and degradation products were detected in soil and groundwater at the site.

The Site is located in a commercial district near the intersection of San Bruno Avenue West and El Camino Real. The Site was occupied by the existing commercial store building in a strip mall shopping center prior to 1949 according to historical Sanborn fire insurance maps. We understand that G.W. Williams has owned the subject property since circa 1950. Apparently, the Williams family developed Camino Plaza along with the Mills Park housing tract in the late 1940s to early 1950s. Historical telephone directories indicate that the Mills Park Cleaners has occupied the store since circa 1981. In 1976, the Mills Park Cleaners & Laundry is listed as the occupant of the building. The current tenants, Mr. Juwon & Mrs. Sam Hahn leased the Mills Park Cleaners facility beginning in February 1987. The previous tenant of Suite 709 was In Sik & Chong Suk Park who operated the facility from circa 1980 through 1987. Prior to 1980, the former operator is believed to be Michael Barrese. Reportedly, Suite 709 has been continuously used for a dry cleaner facility since circa 1948. According to Sam Hahn, when they initially moved into Suite 709, the existing dry cleaning machine was less than five years old. However, the Permac machine was an older transfer type machine with three separated units prone to releases of Perchloroethylene (Perc or PCE) to the surrounding floor. Two photographs in Appendix A show the main clothes cleaning machine, sniffer unit, and distilling system of the in-place old machine. Significant staining of the underlying concrete floor is evident in these photos confirming Juwon & Sam Hahn?s account that Perc spills to the concrete floor had occurred prior to their occupancy. Being knowledgeable of the potential hazards of Perc, Juwon & Sam Hahn purchased and installed a new closed-system Dry-to Dry machine (with a secondary containment pan) on September 12, 1987. A photograph of the new machine being delivered to the Mills Park Cleaners facility is shown in Appendix A (Photograph No. 6). Since their occupancy in 1987, Juwon & Sam Hahn have been permitted and inspected by the San Mateo County Health System with no reported releases or other violations. They have records indicating their conscientious disposal of waste Perc from the dry cleaning machine by Technichem and Safety Kleen. In 2007- 2008, Sam Hahn voluntarily replaced the PERC machine with a hydrocarbon based dry cleaning machine. Additional photographs in Appendix A show the new machine installed in the facility. Two Leaking Underground Storage Tank (LUST) cases are located on El Camino Real near the Mills Park Cleaners facility (Photograph No. 2, Appendix A). The Gootnick Property at 732 El Camino Real and Melody Toyota and 750 El Camino Real have ongoing groundwater investigations. Groundwater measurements at these LUST cases indicate that groundwater is flowing underground from the subject property towards El Camino Real. The discovery of PCE contamination in groundwater at these two sites indicates that PCE contamination may be originating from the vicinity of the Mills Park Cleaners facility. In their November 4, 2005 document titled Subsurface Investigation and Risk Assessment Report, Cambria ?recommends investigating the Mills Park Cleaners as a potential upgradient source of PCE by completing additional subsurface investigation activities upgradient of the site.? The San Mateo County Groundwater Protection Program (GPP) requested groundwater sampling down-gradient from the dry cleaner facility. Sam Hahn subsequently submitted the analytical results of the April 9, 2009 grab groundwater sample requested by the GPP. The sample revealed a concentration of PCE in groundwater of 280-∞g/l that is above the Environmental Screening Level (ESL). Because Mills Park Cleaners is the current business owner-operator at the property where the groundwater contamination was discovered, GPP staff named Mills Park Cleaners as a responsible party for corrective action. Other potential Responsible Parties identified in this search consist of the former operator of Mills Park Cleaners named Insik Park (from circa 1980 to 1987); and the historical operator prior to circa 1980 named Michael Barrese. Based on the documentation provided by Mrs. Sam Hahn, it appears reasonable to expect that PCE releases to soil (if any) and groundwater at the site will be associated with pre-1987 chemical storage, handling and disposal practices. As presented in the San Mateo County Health System Letter, dated August 6, 2009, GPP staff also named G.W. Williams & Co. as a responsible party for corrective action. Based on their history of conscientious chemical housekeeping since 1987, lack of violations, and installation of a closed-system dry cleaning machine with secondary containment in 1987, Ms. Sam Hahn requests that the current operator of Mills Park Cleaners not be listed as the primary responsible party for the corrective action at the site, and that it would be more appropriate for the owner and past operators of the dry cleaning facility to be listed as the primary responsible party, since the history of transfer-type dry cleaning machines with Perc spillage to the floor prior to 1987 would be the likely cause of any soil and groundwater contamination at the site.

The subject property is located in a commercial/industrial area of San Carlos on the south side of Bransten Road, between Old County Road to the west and Industrial Road to the east. The subject property consists of one (1) commercial parcel (APN 046-133-100) of approximately 48,400 square feet which appears to slope slightly to the north. An asphalt-paved driveway which is also used as tenant parking separates two (2) existing single story commercial warehouse buildings of approximately 13,500 and 12,150 square feet, identified as 1007 and 1011 Bransten Road, respectively. During the period November 2008 through August 2009, GEI completed a Phase I environmental site assessment, two (2) subsurface investigations and an indoor air investigation at the subject property. The subject property history is detailed in GEI?s Expanded Site Investigation. This report also documents the second subsurface investigation completed by GEI at the subject property. The subsurface investigations discovered elevated concentrations of diesel to oil-range petroleum hydrocarbons, lead and cadmium in soils beneath the concrete floor along the eastern edge of the subject property in the 1007 Bransten Road building. The diesel to oil-range petroleum hydrocarbons, cadmium and lead were detected in some soil samples at concentrations exceeding Regional Water Quality Control Board (RWQCB) Environmental Screening Levels (ESLs) for both residential and commercial/industrial soils, independent of whether groundwater IS or IS NOT a potential source of drinking water. Lead was detected in a soil sample at a concentration exceeding California criteria for hazardous waste. The impacted soils were found at depths just below the approximate two (2) feet of fill placed prior to construction of the 1007 Bransten Road building, to a depth of no deeper than approximately eight (8) feet below top surface (bts). The lateral extent of significantly impacted soils in a westerly direction appeared to be not greater than approximately 20 feet westerly from the eastern wall of the 1007 Bransten Road building. The lateral extent of impacted soils in easterly, southerly and northerly directions had not been determined. The subsurface investigations also discovered soil impacted primarily with tetrachloroethylene (PCE) at concentrations exceeding RWQCB ESLs for both residential and commercial/industrial land use beneath a concrete and asphalt surfaced area on the west side interior and exterior of Unit F of the 1007 Bransten Road building. The lateral extent of significantly impacted soils had been defined by GEI to the east, south and west, but not to the north. Based upon GEI?s findings and conclusions, GEI recommended further characterization of soils in the 1007 Bransten Road building to determine the full lateral extent of the significant diesel to oil-range petroleum hydrocarbons, cadmium, lead and PCE-impacted soils on the subject property.

The site is located in a commercial portion of Redwood City and is bordered to the southwest by train tracks, to the northwest by an attached commercial building, to the east-northeast by Arguello Street, and to the southeast by Brewster Street The site building, approximately 4,600-sguare-foot single story structure, is currently divided into three sections, each occupied by three different businesses. The middle section of the building (707 Arguello Street) where the former Style Cleaners was formerly located is a silk screening business. The southeast portion of the building (701 Arguello Street) nearest the corner of Brewster and Arguello Streets is a coin-operated laundromat facility, and the northwest portion of the building (713 Arguello Street) is occupied by a beauty salon. The former Style Cleaners occupied the property from 1960 through 1990. In May 2008 soil samples collected from two borings advanced to a depth of 10 feet contained up to 7.1 mg/kg of PCE at 5 ft bgs.

Goss-Jewett owned the Site from 1957 to 2011 and operated a dry cleaning supply distribution business from 1957 to 2000 at the Site. The company provided laundry chemicals, including detergents and spotting chemicals, packaging products such as hangers and polyethylene bags, and bulk deliveries of tetrachloroethene (PCE). The PCE was stored in a 4,100 gallon aboveground storage tank (AST) that was in the southwestern corner of the building. In 2000, the Site was leased to Pain Therapeutics, which converted the warehouse into office space. The Site is currently operated as B.I.A. Cordon Bleu, a wholesale manufacturer and distributor of porcelain and stoneware, bakeware, and dinnerware. There were no reported spills or releases from the Site during Goss-Jewett?s operations. There has been no known use of chlorinated solvents at the Site since Goss-Jewett ceased operations in 2000. The initial investigation of the Site was conducted by Geomatrix on behalf of Goss-Jewett in response to a directive from the Regional Water Board dated May 14, 2007. The Regional Water Board was overseeing the investigation of the release of volatile organic compounds (VOCs) in the vicinity of the neighboring property located at 290 South Maple Avenue, which is adjacent and east of the Site. Since the Site was previously a dry cleaning supply distribution business, and it is located up-gradient and cross-gradient of 290 South Maple Avenue, the Regional Water Board directed Goss-Jewett to investigate the Site for the presence of VOCs. The results of the 2007 investigation confirmed the presence of highly- elevated concentrations of VOCs, including PCE and its breakdown products, at the Site. The results of additional investigations have confirmed the presence of highly-elevated concentrations of VOCs in soil, soil vapor, and groundwater samples collected in the southwestern portion (former AST area) and the northeastern portion of the Site. * Other Means HELEN'S CLEANERS 1594 WOODSIDE ROAD REDWOOD CITY CA Cleanup Program Site Open - Site Assessment SAN MATEO COUNTY LOP Tetrachloroethylene (PCE) Other Groundwater (uses other than drinking water) Extracted from AllWest's November 29, 2007, Workplan Additional Site Characterization. San Mateo County does not take responsibility for the accuracy of the statements made or any professional interpretations made in the referenced report. Woodside Shopping Plaza is located in a mixed residential and commercial area of Redwood City on the west side of Woodside Road. The subject property is bounded by residences to the north and west, retail businesses to the south and Woodside Road and retail businesses, including a Shell service station, to the east. The subject property was vacant and undeveloped prior to construction of the existing shopping center beginning in the 1950s. A Union gas station was present on the northeast comer of the subject property from approximately the 1960s to the early 1990s. Historical documents indicated the presence of dry cleaners at the subject property from at least the 1960s. The subject property is currently developed with eleven single-story commercial buildings which comprise approximately 171,832 square feet of leaseable space. The surface topography of the site is relatively flat, sloping gently to the northeast Hazardous material use and storage at the subject property is limited to the dry cleaning facilities Helen's Cleaners and Fashion Cleaners. Both facilities utilize closed-loop drycleaning units (DCUs) with vapor recovery systems. Tetrachloroethene (PCE) is contained within the DCUs. Approximately 20 gallons of PCE are added to the DCUs every 4 to 6 months by an outside contractor. No addtional PCE is stored onsite. The DCUs are located within secondary containment. No significant staining or evidence of leakage was noted in the vicinity of either DCU. Both facilities have spotting stations where small quantity containers (1 -gallon or less) of spotting fluids are used and stored. In November 2002 MACTEC, performed a Phase I Assessment of the property. Because of the long-term use of PCE at the two cleaners a Phase I1 Investigation was performed by MACTEC consisting of drilling and sampling of two geoprobe borings at each dry cleaning facility. Analytical testing detected PCE in soil and groundwater samples. No other volatile organic compounds (VOCs) were detected. To further investigate the extent of the PCE in the subsurface, MACTEC performed an additional investigation in December 2004 advancing nine borings and collecting soil, groundwater and soil vapor samples for analysis. PCE was not detected in any soil samples analyzed. Trichloroethene (TCE), a PCE degradation product was detected in one soil sample at low concentrations. PCE was detected in five of ten groundwater samples at relatively low concentrations. PCE and various petroleum hydrocarbon constituents were detected in shallow soil vapor samples, however, because of the procedures used to collect these samples, the results were not accepted by the GPP. On February 9,2005 the GPP issued a letter to Kil Kwak, Helen's One Hour Cleaners and Woodside Property Manager, TSC Woodside Plaza, LLC requesting further investigation at the subject site. On August 8,2005, AllWest submitted a Subsurface Investigation and Conduit Assessment Workplan. This work plan was accepted with minor revisions by the GPP. In January 2006 AllWest supervised the drilling, logging and sampling of ten Geoprobe boreholes as shown on Figure 2. Selected soil and "grab"groundwater samples were collected and analyzed for the presence of halogenated volatile organic compounds (VOCs) including PCE and its common breakdown products. PCE was detected in all eight soil samples analyzed at concentrations from 0.059 milligrams per kilogram [mglkg, equivalent to parts per million (ppm)] to 0.55 mglkg. No other VOCs were detected in soil samples. PCE was detected in seven of the ten groundwater samples at concentrations fiom less than < 0.5 micrograms per liter (ug/l), equivalent to parts per billion (ppb)] to 260 ug/l. Very low concentrations of acetone 6.1 ug/l to 8.2 ug/l, toluene 2.5 ug/lto 7.5 ug/land xylenes from 1.7 ug/lto 6.8 ug/l were also detected in groundwater samples. Two soil vapor surveys have been conducted at the property; by MACTEC in 2004 and AllWest in 2006. MACTEC data were deemed not acceptable by the GPP due to procedural problems. The results of a soil vapor survey conducted by AllWest in 2006 indicate the presence of a leak(s) in the soil vapor collection system. Results are considered suspect and should be used for comparative screening purposes only. As part of AllWest assessment a preferential utility pathway investigation was performed. Based on maps and information supplied by subsurface utilities owners the maximum depth of utility trenches at the site is eight feet. Groundwater at the property has been measured at approximate depths of 15 to 20 feet. Based on the separation of the utility trench fiom groundwater no preferential pathway exists for groundwater. Subsurface utilities may provide a preferential pathway for soil vapor migration. In summary AllWest's and previous sampling data indicate PCE releases have occurred at the two dry cleaning facilities and impacted soil and groundwater. The exact release mechanism have not been identified but spills and leaks of PCE during dry cleaning operations is likely. Details regarding the previous investigation are presented in AllWest's Subsurface Investigation Report, Woodside Plaza, Redwood City, California, September 12, 2006. * SA Brusco Property 248 Harbor Blvd. Belmont CA Cleanup Program Site Open - Site Assessment SAN MATEO COUNTY LOP Tetrachloroethylene (PCE) Site opened 12/9/2010 due to PCE contamination.

The release of 20-30 gallons of PCE from the PCE still equipment, located inside the building, occurred on November 23, 2005. Representatives of the City and County of Santa Barbara responded to and investigated the spill. The initial investigation revealed a "contaminated" floor area measuring 20' by 30' around the washer/still machine, a floor safe partially filled with dry cleaning solvent, interior floor contamination extended to the boiler room (did not enter boiler room), and a four foot square area of dark stained soil was observed below the guardrail adjacent to the asphalt curb in the alleyway behind the facility. Cleanup activities were implemented the following day (November 24, 2005), and included soil removal and interior floor cleaning. Approximately 60 cubic feet of soil was removed (post excavation samples resulted in a PCE concentration of 0.150 mg/L). The interior floors were cleaned using Simple Green, a pressure washer and a vacuum collection device. From the initial spill investigation until sometime before December 2008 the County of Santa Barbara Fire Site Mitigation Unit (SMU) was the lead oversight agency for this site. A September 2006 workplan (Tetra-Tech) was approved by SMU staff. The Water Board issued Draft CAO No. R3-2008-0091 in 2008 after the site was referred to them from Santa Barbara County. Campbell Geo Inc., implemented an additional site assessment in April 2010. Sampling results for the additional assessment were soil PCE concentrations detected below County Fire investigation standards, but concentrations of PCE in groundwater were 270 ppb (exceeding the regulatory threshold of 5 ppb). Results of this investigation are documented in the "Additional Site Assessment" report dated August 16, 2010. The Water Board issued a directive in September of 2010 to implement the recommendations of the August 2010 report (additional soil and groundwater assessment and a soil vapor survey to further characterize potential impacts at the Site). Recommendations were not implemented, and the Water Board issued a Notice a Violation (NOV) in January of 2012. Geosyntec was retained in August of 2012 to address the directives of the Water Board and respond to the NOV. Site investigations that were carried out from 2013 to 2014 by Geosyntec resulted in the following site characterization: -PCE CONCENTRATIONS IN SOIL - max PCE concentrations in soil were detected beneath the slab adjacent to the dry cleaning machine (VP-04) at a concentration of 630 micrograms per kilogram, and in the alleyway approx. 60 feet southwest of the dry cleaning machine at depths of 15 and 20 ft bgs (440 and 330 micrograms per kilogram respectively). These concentrations are below industrial soil Environmental Screening Levels (ESLs) for PCE of 700 micrograms per kilogram. -PCE CONCENTRATIONS IN SOIL VAPOR - max PCE concentrations in soil vapor were detected in December 2013 concentrations of 1,500 micrograms per liter in VP-17 at 30 ft below ground surface (ft. bgs), and 1,250 micrograms per liter in VP-04 at 3 ft bgs. Commercial ESLs for PCE concentrations in soil vapor are 2.1 micrograms per liter. -PCE CONCENTRATIONS IN GROUNDWATER - quarterly groundwater monitoring from December 2012 through June 2014 resulted in PCE concentration detections ranging from 1.8J to 1,300J micrograms per liter. The highest PCE concentrations are present in MW-02. PCE concentrations exceed State of California Maximum Contaminant Level (MCL) of 5 micrograms per liter in wells MW-01, MW-02, MW-03, MW-04, and TSG-MW-27. Based on the site characterization, it appears spills or leaks from the dry cleaner caused soil gas and groundwater impacts, and not just the 2005 leak. Water Board staff are working with the responsible parties to start cleanup of the source area. The current plan is to implement soil vapor extraction on the property.

Groundwater samples contained PCE up to 690 parts per billion. Soil samples contained PCE up to 34 parts per million. Soil vapor samples contained concentrations of PCE up to 5,100,000 ∞g/m3. Investigations are ongoing to determine the full extent of PCE contamination. Shallow groundwater is not currently used for drinking water in this area. The City of Milpitas supplies drinking water to the public. The proposed cleanup plan consists of soil vapor extraction and treatment. Soil vapor extraction wells have been installed below the former dry cleaner. A vacuum pump draws soil vapor from the wells to a carbon-filter treatment system located in the parking lot. Additionally, to protect indoor air quality, the concrete floor in the fitness center has been treated with a vapor retardant epoxy sealant, all accessible floor penetrations have been sealed, and the ventilation system has been optimized to provide fresh air into the fitness center. Soil vapor and indoor air samples will be collected to document the effectiveness of these measures. Once the extent of groundwater contamination is defined, a groundwater cleanup plan will be submitted to the Regional Water Board for review.

The proposed cleanup plan consists of enhanced bioremediation which involves injecting a carbohydrate solution into tetrachloroethylene (PCE)-contaminated soil and groundwater to enhance the natural breakdown of the PCE. We invite any interested parties to comment on the proposed cleanup plan. Written comments are due to the Water Board at the above address by February 27, 2009. BACKGROUND The Site is an approximately 3-acre parcel that is near the northwest corner of East Arques Avenue and Lawrence Expressway (see Figure 1, Site Plan). The Site was formerly used for semiconductor manufacturing by Monolithic Memories, Inc., and Advanced Micro Devices, Inc., (AMD) from 1970 to 1989, and has been vacant since 1991. TWC Sunnyvale, LLC, is planning to build a self storage facility at the Site. During building demolition activities at the Site on July 15, 2005, a single transformer containing PCE was punctured by demolition equipment, releasing approximately 250 gallons of PCE to the ground surface, and subsequently to the subsurface. The Water Board is the lead agency overseeing soil and groundwater investigation and cleanup at this Site. SITE INVESTIGATIONS Multiple investigations have been conducted at the Site prior to and following the PCE spill incident that have defined the extent of soil and groundwater contamination beneath the Site. Soil contamination is limited to onsite areas. The groundwater contamination plume from the Site commingles with another plume from the National Semiconductor Corporation to the south, and extends offsite north towards East Duane Avenue. Shallow groundwater beneath the Site is not currently used for drinking water. The City of Sunnyvale supplies drinking water to the Site and the vicinity. PREVIOUS REMEDIAL ACTIONS Groundwater cleanup by AMD and others has been on-going at the Site since 1986. During the initial response to the transformer PCE release, soil excavations were conducted to remove PCE-affected soil. A chemical oxidant was then injected into the groundwater to aid in the remediation of PCE-affected groundwater. A dual-phase groundwater and soil vapor extraction and treatment system (DPE) operated at the Site in 2008 to treat the remaining affected soil and groundwater at the Site. The Water Board approved shutdown of the DPE system after it was demonstrated that the soil cleanup standard for PCE had been achieved. In addition, AMD recently excavated and removed VOC contaminated soil from other areas of the Site. PROPOSED CLEANUP PLAN The proposed cleanup plan consists of enhanced bioremediation. This involves injecting a carbohydrate solution into PCE-contaminated soil and groundwater to enhance the natural breakdown of the PCE. The carbohydrate solution acts as a food source for the naturally occurring microbes that live in the subsurface. These microbes break down the PCE into harmless byproducts. The carbohydrate solution will be injected through 10 injection borings, each to a depth of 18 feet below ground surface. Groundwater monitoring will continue to evaluate the effectiveness of the cleanup plan until Site cleanup standards are met. * Other Means CITY OF SUNNYVALE PUBLIC SAFETY DEPARTMENT, AND AMD, THE FORMER OWNER OF THE PROPERTY NOTIFIED THE WATER BAORD. removed damaged transformer Ritz Cleaners (Former) 526 S.

In addition to the dry cleaners facility at McClellan Square, the center includes several freestanding buildings: a "Lucky" supermarket (10435 S. De Anza Blvd), "CVS" drug store (10455 S. De Anza Blvd), "Far East Bank" (10465 S. De Anza Blvd), and a "Key Point Credit Union/ Better Home and Loan" (10495 S. De Anza Blvd) with remaining stores located within a strip mall-like structure, adjacent to the southern wall of the CVS drugstore. As part of a due-diligence process for a real estate property transaction Moore Twining performed a Phase I Environmental Site Assessment (Phase I ESA) for the site in Oct 2010. That assessment identified the McClellan Sqaure Cleaners in operation at the site since 1989. Prior, the facility operated as another dry cleaner from 1970 to 1989. Concentration of 47 ug/kg (miligrams per kilogram) PCE were detected in soil samples collected during installation of MW-1 (monitoring well) at depth of 15 ft. below ground surface (bgs). Non-detects were reported for VOCs from depths of 15 to 90 ft bgs at this location (MW-1). Additional soil sampling and indoor air quality assessment were performed in February 2011. Results indicated PCE concentrations at 130 mg/kg in 15 ft bgs soil sample in vicinity of existing dry cleaning machine. Results of the inddor air assessment indicated PCE concentrations exceeded screening levels published by California Environmental Protection Agency (CAL-EPA), the California Regional Water Quality Control Board (CRWQCB), and California Prop 65 "No Significant Effect Concentration". Horizontal extent of PCE soil gas concentrations above CHHSL and ESL values was found to extend under building slab to a minimum of 60 ft north (VMP-7)and 60 ft south (VMP-9) of existing dry cleaning machine. PCE concentrations below commercial CHHSL and ESL values were detected in soil gas in the eastern parking lot (VMP-4) about 80 ft east of existing dry cleaning machine. An in-situ SVE (Soil Vapor Extraction) system was recommended to be an appropriate and cost-effective interim method to remove PCE in soil and vapor at the site and to reduce the previously identified risk to indoor air quality.

Dilute tetrachloroethene (PCE) detected in groundwater during Phase II site investigation in April 2004. PCE was not detected in any of the soil samples. In August 2006, two additional shallow soil samples were collected from hand-borings, results were inconclusive. No actions or investigations occurred from May 2008 to October 2014. A limited Phase II investigation was conducted in October 2014. A follow-up indoor air investigation was conducted in February 2015. Analytical data indicates there is no soil pollution at the Site from previous dry cleaning activities. The Site and surrounding area is located within and service by the City of Redding public water system, there are no downgradient sensitive receptors and the October 2014 sampling results showed PCE has attenuated in the groundwater. Air monitoring results indicate that vapor intrusion of the volatile organic compounds associated with previous dry cleaning activities is not occurring at the Site. No further action is required and the case was closed in June 2015. * Other Means PCE AT 47 PPB IN SHALLOW GROUNDWATER (16.5 FOOT DEPTH) IN A BORING APPROXIMATELY 2O FEET FROM THE FRONT OF REGAL CLEANERS.

Discharger sampled off-site soil gas; a qualified toxicologist reports no threats to off-site indoor air. Discharger injected emulsified soybean oil for bioremediation of the near-source aquifer. Follow-up monitoring showed that injection induced serial reductive de-chlorination of the PCE into daughters. The affected private well owner voluntarilly installed an in-home activated charcoal filter. Down-gradient limit of plume is defined to the extent practically feasible. Based on preliminary modeling, plume is likely stable. Pollutants likely discharge in the subsurface from the low-permeability Red Bluff Formation, and further disperse into higher permeability gravels of the Sacramento River floodplain. With related increased dispersion, pollutants are likely dilute in the gravels. Discharger has monitored groundwater in the Red Bluff Formation near its contact with the gravels.

VENTURA CA Cleanup Program Site Completed - Case Closed Tetrachloroethylene (PCE) Aquifer used for drinking water supply The Site is located in the Lower Ventura River Basin. According to the Department of Water Resources Bulletin 118, the uppermost groundwater bearing unit is an alluvial deposit that extends to a depth of 60 to 100 feet overlying the San Pedro Formation. The regional groundwater flow direction is towards the south. Based on eleven soil boring logs, the Site is underlain by alluvial deposits consisting of interbedded silts, clays and sands. Groundwater at the Site is encountered at a depth of 20 feet below ground surface (bgs)). The subject site consists of a vacant commercial unit formerly occupied by Crystal Dry Cleaners. The building hosting the former dry cleaners was demolished and redeveloped into a new shopping center. The site assessment determined that tetrachloroethylene (PCE) has impacted both soil and groundwater beneath the Site and identified the dry cleaning operation as a potential contaminant source. It is reported that during redevelopment activities at the Site, a total of 466 tons of PCE impacted soil was removed and the excavation was backfilled with clean soil. Soil samples were obtained from 11 soil borings at the Site and yielded concentrations of PCE ranging up to 1,100 micrograms per kilogram (╡g/Kg). Based on the information provided, the PCE plume in soil is centered beneath the former dry cleaning machine which is identified as a potential PCE release point. In addition, a 48 hour vapor extraction test was conducted using 5 wells. Groundwater investigation was also conducted with the installation of three groundwater monitoring wells in 2003 and two groundwater monitoring wells in 2007. The wells were sampled periodically.

The former depot consisted of approximately 486.9 acres of land and was bounded on the north by Fruitridge Road, on the east by Florin Perkins Road, on the south by Elder Creek Road, and on the west by the Southern Pacific Railroad tracks. In 1995 the SAAD was closed as a part of the Base Realignment and Closure (BRAC) process. Most of the former depot is now owned by commercial firms and the City of Sacramento, with smaller parcels retained by the Army, the U.S. Navy/Marines, and the California National Guard. All properties in the former depot are zoned commercial/industrial or agricultural/open space. The former depot was an electronics and maintenance facility and was established in 1945. Residues from metal plating and painting operations were disposed of in oxidation lagoons and burn pit sites. Contaminated media includes site soils and the groundwater beneath the southwestern portion of the site extending down gradient some 2,000 feet to the south. Chemical contaminants detected in the soil and groundwater includes metals and volatile organic compounds (VOCs), including; carbon tetrachloride, trichloroethene (TCE), tetrachloroethene, 1,2-dichloroethane, and cis-1,2-dichloroethene (cis-DCE). The remedies selected for SAAD addressed soil and groundwater contamination. The South Post Burn Pits Operable Unit (OU) was remediated with a combination of soil vapor extraction and soil excavation/stabilization. The Corrective Action Management Unit (CAMU) is sited at the South Post Burn Pits OU and it received soils from this site, as well as the others sites described below. Soil excavation, stabilization, and consolidation in the CAMU were also the remedy chosen for the Oxidation Lagoons OU, the Battery Disposal Well (Investigation-Derived Waste), and Building 300 Burn Pits. The Parking Lot 3 Groundwater site was remediated with a combination of air sparging, dual-phase extraction, and groundwater extraction with wellhead treatment via carbon adsorption. Groundwater extraction with ultraviolet light and chemical oxidation treatment was the remedy selected for the South Post Groundwater OU. The soil remedies are complete with all stabilized soils consolidated within the CAMU. Groundwater extraction and treatment has ceased at the Parking Lot 3 Groundwater site, although discussion and evaluation continues regarding the success in meeting the remedial action objectives. Groundwater extraction continues at the South Post Groundwater OU. The extracted water is discharged directly to the sanitary sewer under permit. Ongoing evaluations are continuing on the following issues; 1) optimization of the groundwater treatment plant, 2) effectiveness of the present remedy and 3) evaluation of alternatives to the present remedy that would prove more effective at meeting the ROD requirements. Institutional controls are in place and currently enforced.
